mine did it within two days basic driving didnt have to do any extra steps.. just drove to the store, got gas, some food, came home in less than 15 miles all were good to go except evap... next day went to work came home evap was good to go.. all within 25 miles and didnt even get on the highway
@@KrGsMrNKusinagi0 300 miles and the testing facility says mine isn't ready. My scanner says everything is fine, or rather 2 scanners say everything is as should be. Wonder why?
On my 99 tahoe, 420 miles and the evap is still incomplete, did all the drive cycle, drove in town, hwy over a 4 weeks period. Now need to wait for appointment at dmv to get another moving permit....
2021 Chevy Traverse passed after watching this video! Drove 800 miles , gas and nothing smh. Was about to give up. did this to the Tee! Less than an hour Greatly appreciate you !
I did this drive cycle this morning after driving all day with three of my sensors not ready. After doing the drive cycle, the final two sensors turned ready and I can have my inspection the following day. I appreciate the walkthrough and explanation. For me, the success of the drive cycle was the upon cold startup, turning on the defroster, AC…anything that can put as much electrical load on the system as possible. I didn’t do this prior and it made for a long day. Also it is truly best to do the drive cycle early in the morning or late at night, preferably on the weekend as it’s when a lot of people sleep in. It made for a lot less concern and anxiety if you can only do this on a road that is often traveled at 65 mph minimum.
Gm, here in Ohio. Thank you very much for the information. I have a Chevy Malibu that failed emissions 3x and I followed the drive cycle as instructed. Once going to another emission location, I was able to pass the test. Again, thanks!
Stanford, I'm glad to the video was helpful on your Chevrolet Malibu smog and it help you pass. I really appreciate you taking the time to post this. Thank you
Thank you! I just passed my smog (Class C motorhome on a 2000 Chevy Express chassis with the 7.4 liter V8). This video helped me get ALL my monitors ready (even the Evap System) in one trip, without a lot of gasoline expense and extra stress. Thanks again!
I finally got the drive cycle completed for my 2016 Chevy Tahoe. Great instructions. Just a couple things I had to do differently. My O2 sensor would not set while I was trying to performing my drive cycle. I was about to give up and parked, let the car idle for a few minutes with the air and defrost on and turned off the vehicle. I waited a few minutes and started driving at 55mph for 3 minutes with no aie or defrost and it set. Each time I allowed the car to coast below 20mph, I pressed the brakes before I started the next step in the drive cycle. (Before when I didn't hit the brakes below 20mph, it would not set) I also purchased the ob2 reader you recommended and it's so much easier I don't have to manually hitting the buttons and keep checking the meter.
Thank for sharing your success on your 2016 Chevy, yeah the extra load from the air conditioning and rear defrost really helps with o2 monitor. This o2 trick is used mostly on honda but I’m see success with on all makes and models. Thank you again for taking the time to post your experience.
This video is outstanding. Had recent repairs to my chevy silverado 2500hd and was due for smog here in Cali. The smog place wanted me to drive 200+miles over the course of 15 drive cycles to get all the systems set. Found this video and got almost all sensors done in less than an hour. The only one sensor that hasn't set is the O2 sensor heater. Will try a cold start again once it's ready. Thank you for making this video!
You're a genius! Thanks so much for this video. I drove around for a few hours trying to get the o2 sensor heater monitor ready. This morning I started my '99 Suburban; turned on the A/C, rear defrost, headlights and the o2 sensor heater monitor was ready in just under 2 minutes! Liked, subscribed and "Super Thanks"ed (from my other Google account)👍
You did a lot of work here to deliver some essential information -- much appreciated. I am learning the hard way, DIY ain't what it use to be. When I started working on my cars, who would of thought a technician degree would be a requirement for a tune up. Thanks again.
Lol, here I will show to complete the drive cycle ua-cam.com/video/jldTJI64cfM/v-deo.html Please note that your vehicle drive is a little different from I show because you are driving a gm. Good luck!👍🍀
Thank you for this video! I only wish I would have found it before I wasted $80 on gas driving around aimlessly trying to ready the o2 sensor heater monitor. 🤬🤣 Have a awesome day and keep up the great work!
Glad to help and thank you for the support. The heater monitor should run first and should set really fast on your Chevy. I made an update to the o2 sensor video ua-cam.com/video/Yn1-ul62Jio/v-deo.htmlsi=6HmUbXote9z6VemE Thanks again
It finally set the EVAP, after 2 run cycles I went to start it to do another run cycle and checked scanner and the EVAP was set. Thanks again!@@RANDOMFIX
In California they allow the evap not to be completed. But if you had a previous evap code you repaired and cleared all DTC’s it still stores in the I/M trouble codes as a permanent code until the evap monitor has completed and no DTC is set to verify repairs have been made. They will fail you even if there’s nothing wrong with the vehicle and you have no codes present.
Yes you are right but there is still a way around as the the allow for the 15/200 rule. I explain in in this video ua-cam.com/video/wcCRN_c6Mss/v-deo.htmlsi=CA7MXfPC5LLuf2J2 It’s very easy to meet this criteria. Thanks for sharing
@@RANDOMFIX failed me out right today due to a “ permanent code” for a fuel pressure sensor that I just replaced. Went to BAR’s website today and found out the cause is because permanent codes cannot be cleared manually only the ECM can clear them once the monitor is completed and it verifies the repair has been completed. I don’t smog cars anymore it’s been some time and apparently this is a new thing started in 2019 affecting vehicles from 2011 and newer. BAR states it’s a issue they are currently working on with the state of California because it’s causing some issues. From what I see it wasn’t the shop that failed me it was automated by the smog machine. I just watched your video about the 15/200 rule, I did read that on BAR’s website as well. Thank you for your reply and your videos
Thanks it worked for my 2019 chevy malibu. Failed emission twice after following your instructions it passed. My mechanic put me in the right direction to look into drive cycle. Thank you. Ps issue was due to me disconnecting battery because. I had a p1101 fault, I did resolve the code issue first.
Good luck with it and let me know if you have any questions. It’s not as bad as it seems, here is an example ua-cam.com/video/jldTJI64cfM/v-deo.htmlsi=anVNGILC4za_FFKq Let me know if you have a specific questions. Complete2 drive cycles and then focus only the unset monitors
Dear Sir, This video has provided me with remarkable amount of knowledge of the smog process. Fantastic information. I have a problem with the procedure for a 2017 Chevrolet SS Sedan. Battery was replaced and the dealer Cleared all codes and has been unable to get this car to pass smog. Any specific data to support GM ODB2 driving cycle reset procedure 2017 Chevrolet ss Sedan. Please advise.
Complete two drive cycles on your ss sedan and then focus on the unset monitors. I show the drive cycle on this video ua-cam.com/video/jldTJI64cfM/v-deo.htmlsi=MbtICN8aQnCVk8MC This is a general drive cycle and should work for your Chevy as it’s less than 10 years old.
@RANDOMFIX Thanks you the easy to follow steps. I had to change out my battery, and could not figure out how to get this aggravating thing ready. One thing, I assume these test do not have to be run together. I live in the city, and it is hard to find a place I can run 55 mph 3 to 5 minutes straight. So, I'll have to drive to different highways to get them all done.
Had a catalyst monitor that wouldn't set (2007 Tahoe) but your video info worked in just 45 minutes. BUT, I then stopped and filled the gas tank, upon leaving the DIC started saying over and over that the stabilizer system was off, so, I then stopped and shut off the engine and the stabilizer thing went away but now have 4 monitors that are not set including the catalyst one. Maybe a ground? I am at a loss.
Yeah I have heard of monitor information getting lost after each turn off so yes it could be a ground. The question is if you set a monitor now and turn off the vehicle will it lose the monitor data again?
@@RANDOMFIX Right, I need this vehicle, so I am cleaning up all the grounds I can find, and adding a few to any ground wire I can find. It was a Michigan car, now Arizona, has rust and corrosion in places. Adding grounds body to frame, body to engine. I assume the main ECU is the fault because there are several different types of monitors that now need setting. So I will try to find a wiring diagram and try to re-ground it, the OBD2 port did not work at first, so I unplugged then replugged in the big cable bundle connectors on the ECU and now it works. I have since blown it out with air and replugged it several times to kind of clean the terminals on the connectors. Any advice would be helpful.
For me I kept having an issue where my 09 Denali wouldn't run the readiness test for the catalyst monitor for like a week, turned out I was not letting it get hot enough from a cold start. I let it warm to 190 one day after work and luckily I can hit about 50+ miles an hour as soon as I pull out of the parking lot and it readied all test minus the Evap and the drive wasn't even over 5 minutes long.
I agree .and some of the instructions i cant do correctly cuz i cant get up to speed untill i leave town.. then theres finding a roads without bends that require breaking to reach a safe speed.decellerating is unsafe cuz you cant warn drivers behind you without using breaks. I find it frustrating to say the least.
Man I got 2014 Chevy Silverado been driving around for 3 days 400 miles can se to set I do 1 cold start but still have 3 monitors on I’m keep doing hopefully we get this cleared up 😂
Catalyst hasnt set after following drive cycles. O2 sensors im readiness shows ready. Still think I should follow o2 sensors? 167 miles since codes reset.
If the catalyst is the only monitor left than start the vehicle with air conditioning running and a full extricate load and after 20 minutes take your vehicle on the freeway and get that catalytic converter nice and hot. Hill and mountain will help heat it up. Don’t drive with air conditioning or cruise control Good luck and keep me posted
I have a 2013 Chevy Cruze the o2 sensor monitor is still incomplete. And I can’t run my AC as it needs to be fixed, will my o2 sensor not complete until ac is fixed ?
Thanks for the video. I have a 2007 Sub with only 74 miles. Check engine light turned on with OBD code P0446 (Evaporative Emission System Vent Control Circuit 1/1. I've replaced the gas cap, vapor vent canister valve, vapor jumper wire and the Emissions Vapor Canister Purge Valve Solenoid EVAP Vent ( I don't think it's necessary but I did it anyway). Cleared it and the check engine light is gone but after driving 93 miles, the I/M is still not ready with a combo drive of city and fwy. Drove it for another mile and after 6 cycles, when I ran the OBD at 94 miles to see if it's I/M ready, unfortunately I see the same "pending" P0446 code despite driving it up to 110 miles hoping it will clear on it's own. So I decided to erase the pending code/OBD and did the same thing again. Drove it up to 92 miles without check engine, still not I/M ready and at 94 miles later it's still not ready and the "pending" p0446 code is back. Replaced the vapor vent canister valve, vapor jumper wire again just in case I have a bad part, but unfortunately pending P0446 code is back. I'm hesitating on replacing the vapor canister/charcoal cause I don't have an issue filling up gas and no gas odor around the area too. Could it be the another bad vent valve? fuel tank pressure solenoid? I hope not... cause I know this is pretty common on the 2006 but not on the 2007. Cleared it for the 3rd and 4th time, gas level is between 3/4 or 1/2 and the pending code is on after 10 miles but still not I/M ready. Should I just keep going and repeat the drive cycle until it clears or do I need to change the ftp and the V.C. Charcoal too? I'd really appreciate yours suggestion cause I need to pass smog. One last question below; I heard I can pass with a pending code as long as no check engine light is lit. But can I pass smog with 1 pending code and evap not ready but everything else are?
Yes, you should be good with no check engine light and evap monitor that not ready even if you have pending code. Don't wait too long as the code might trigger the check engine light. If they technician checks with the cheap little scanner before he smogs he may turn you away because he doesn't want it to count against his passing data or stats so then go to another station. I know it's annoying and a waste of time!!!!
man, I can't even pass the emission because the EVAP in incomplete mode.. I drove 110 miles yesterday and nothing changed and now i used to scanner this morning and i accidently hit reset and now the whole smog tests are incomplete ..AHHHH i have appointment with the DMV this monday and i won't be able to get emission test to pass..
Need help I put a new cat on my 2009 Chevy Tahoe cleared the cat and o2 sensor but the o2 heat is still incomplete any suggestions on how to my it ok??
what should i do if i live a 10 min drive to the highway , with lots of traffic lights in between here and there? will it affect my drive cycle to do the cold start, ac running, and then drive in a stop and go manner until i can get to 55mph?
Brother nice video, I only have o2’s and HRT monitors not ready, I could just do the cold start and turn on cold AC and rear window defroster and it should activate right?
Yes and make sure you battery is perfect l, you will need check the battery voltages with the car off after running the headlights for a few minutes to get rid of any surface charger. If that if still doesn’t set check the connectors while the vehicle is off and verify is everything is solid and clean.
All codes cleared. Did the drive cycle in my 2000 S10 V6. Left a comment in another video that you just answered. I only have to get the HTR to set. You said it is the first thing in the drive cycle. Does it set if it is ok after cold start and idle for 2.5 minutes. How far throught the drive cycle do I have to go? I hope not all the way. It seems it will know how long it takes to from open loop to closed loop pretty early on in the test.
It should be one of the first monitors to set. I would check the heater element if it doesn’t get ready soon. It’s easy to do. Just focus on the warm up. ua-cam.com/video/sAvxeAyYsRk/v-deo.html
@@RANDOMFIX It set this morning. Warmed it for 3 minutes, drove around the neighborhood until it came up to temp. Came home, hooked up the scanner and all monitors are set except the EVA and that one does not need to be set in order to pass. So my guess is the o2 sensor heater is something that needs several cold starts before it will set. In my case there were 4. Or maybe the heater is just weak. IDK. But it's all good and I am very happy about that. Thank you for your time.
How does one get the AIR pump ready. Mine simply refuses to be ready. Is it ONLY cold starts or does that monitor require drive cycles? It’s the only monitor I’m concerned with.
Of course i had a check engine light day of smog for a fuel level circuit code cleared the code got all monitors ready except heated oxygen sensor 2009 chevy tahoe how do i ready that one
For the heated o2 just let it ideally normally it’s one of the first monitors to set. This explain a little more in depth. Is the front (pre cat) o2 sensor the original sensor that the Tahoe came with? Has it ever been changed? ua-cam.com/video/Yn1-ul62Jio/v-deo.htmlsi=3EucTwQ1eSaG_dCw
@RANDOMFIX all monitors were ready/ok i had a check engine light on so fixed the light and tried to ready monitors its only been 1 day.. so ill try again today thanks
So I live 2 mins from the freeway should I do the first part of the drive cycle in my driveway or should I start the truck and get near the freeway then start the drive cycle? Thanks in advance 👍
hello I have a Suburban 99 it is time to renew the registration for which I need the smog and after disconnecting the battery for a long time since it is a vehicle that is driven very little and when reconnecting the battery and driving it approximately 200 miles the HTR O2 sensor monitor is the only one that is not complete, I am thinking that it could be the oxygen sensors that are already old?
Thank you. Very helpful. I tried this several times, over the course of several days, but Cat and EVAP is still not setting. All others are set. Not sure if I am missing something. Do I have to start the whole new cycle from cold if I am just trying to get Cat monitor to set or can I just focus on the Cat setting procedure?
@006pup 55 to 60 drive then coast to under 20. Do it a few times n you should be good. Scan tool helps. I leave mine hooked up and I look over occasionally
Focus a proper warm up. Check all the connections on the oxygen, the precat 02 sensor. Look the connectors and make sure they are clean and snug. After your o2 heater sets then your catalyst will set.
Also, up to 2 monitors can be exempt on diesel including the catalyst, for gas only the evap is exempt. I hope that is helpful and keep me in the look.
Great video bro! Any advise for me? I have a 2001 Silverado and just did an engine rebuild. No codes and and monitors passed except the Secondary Air System. It says Not Ready. I have already put 900 miles on the new engine. Anything you can recommend?
2001 s10 2.2L secondary air system monitor does not want to set ive been doing cold starts for the past 2 weeks and nothing no codes no pending faults i changed the check valve etc and still nothing
Could you please tell me what i need to do to get the “HTR” monitors ready? All other monitors are said as ready or N/A 2002 chevy suburban 1500 5.3l v8
This is o2 heater monitor sheikh normally sets first. I would try a few more times but I have seen a lot of these 2000+ hm product act up when the battery is not perfect. I covered this in my last 02 video from last month. ua-cam.com/video/Yn1-ul62Jio/v-deo.html The heater element is inside the the o2 sensor ( upstream ). If the video does not help clarify try testing it ua-cam.com/video/zEbXn6vgqiA/v-deo.html I think it will pass heater test but it could aged. Incase you replace make sure you use an oem sensor. Good luck and keep me in the loop.
I have a 2003 chevy silverado, the only incomplete monitors I currently have are the catalyst and evap monitor. Can I skip the other steps and go straight to the steps to get the catalyst monitor to complete?
The check engine light is not normally triggered by an older power steering system. Maybe on of the newer electric powering steering system may trigger a cel. I would recommend buying a cheap 30 dollar tool. There is a link the video description
Great video! BUT, I can't get my 2000 c3500 7.4l to pass the egr check. I haven't driven the truck in over 2 months, So when I had to jump start the battery my emissions reset. Of course now I have to get a smog test. Do I need to go through a complete drive cycle or can I just focus on one set of parameters to get the EGR test to complete? No mods or anything like that. Thank you in advance and your expertise
Thanks for the feedback, much appreciated, just focus on the egr however make sure your battery is good by using a load tester and not just by checking the surface charge voltage. I would coast from 65 to 1 to 2 mph without using the brake pedal. So find a nice open road and coast. Do this 3 to 4 time recheck the egr monitor. Keep me the loop.
Thank you for the reply. I tried that and drive around over 100 miles. Found areas where I could get to speed and slowly coast. Unfortunately, it didn't work!
Absolutely great video man new subscriber! Couple of questions though. In California 1999 cars are allowed 1 incomplete monitor and the evap is exempt. So if evap monitor isn’t ready and also another monitor isn’t ready does that count as just 1 monitor not ready you think? Or it’s 2 and it’s a fail?
you will need to stop getting that 420 code from being detected before your start your drive cycle. The Permanent solution is to replace the catalyst but that can be expensive. In case the code doesn't pop up right away I would try some of the temporary solution I show here ua-cam.com/video/BuZYAy_xi0E/v-deo.html Good luck and keep me posted on your 1997 GMC safari.
Try this INSPECTION/MAINTENANCE COMPLETE SYSTEM SET PROCEDURE DIAGNOSTIC INSTRUCTIONS Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure. Review Strategy Based Diagnosis for an overview of the diagnostic approach. Diagnostic Procedure Instructions provides an overview of each diagnostic category. DESCRIPTION The purpose of the Inspection/Maintenance Complete System Set Procedure is to satisfy the enable criteria necessary to execute all of the I/M readiness diagnostics and complete the drive cycles for those particular diagnostics. When all I/M monitored diagnostic tests are completed, the I/M System Status indicators are set to YES. Perform the Inspection/Maintenance Complete System Set Procedure if any I/M System Status indicators are set to NO. Inspection/Maintenance Data List To determine if the inspection/maintenance readiness diagnostic tests can be run this ignition cycle, use a scan tool to observe the inspection/maintenance monitor enabled parameters in the inspection/maintenance Data List. CONDITIONS FOR MEETING A COLD START The ignition voltage between 11-18 volts. The barometric pressure is more than 75 kPa (10.73 PSI). The start-up engine coolant temperature is between 4-30°C (39-86°F). The start-up intake air temperature is between 4-30°C (39-86°F). The difference between the IAT and the ECT is less than or equal to 6°C (10.8°F). The ambient air temperature is between 4-30°C (39-86°F). The fuel level is between 15-85 percent. CIRCUIT/SYSTEM VERIFICATION Review the inspection/maintenance system status indicators with a scan tool. All I/M system status indicators should report YES, and no I/M Test DTCs should be present. INSPECTION/MAINTENANCE SYSTEM SET PROCEDURE NOTE: Whenever the ignition is turned ON, ignition positive voltage is supplied to the heated oxygen sensor (HO2S) heaters. After verifying the enable criteria, turn OFF the ignition for approximately 5 minutes to allow the sensors to cool before continuing with the test. Once the engine is started, do NOT turn the engine OFF for the remaining portion of the set procedure. 1. Ensure that the vehicle meets the conditions for a cold start listed above.
exelente video amigo. disculpa amigo tengo una pregunta , tengo mi chevy suburban 2011 LT 3.5 NATURAL ASPIRE. tenia un problema con el monitor del catalisador ,evap y 02S le cambie el catalisador con uno nuevo ,cambie los 4 sensores se los puse nuevo, le canbie la valve Asm-evap emis Cnstr purge Sol, lo lleve al la estacion de la prueva de emission y no me la pasaron hise el prosedimiento que tu explicas y otra vez no paso emissiones locorry tres veses igual como explicas lo lleve otra vez y no volvio a pasarla. el monitor del catalizador lo tiene listo pero me quedan 2 pendientes y ya trate de todas forma y nada me podrias ayudar con agun tip de algo que le pueda estar fallando al evap o alos sensores y si tiene algo que ver que si no funciona el evap tampoco funcionara el 02S ? ahora tengo cierta informacion que te ayudara a descubrir realmente la falla.

GRACIAS POR TU AYUDA Y NO SE SI HABLAS ESPANOL PERO GRACIAS POR TODO Y ME PUEDES RESPONDER EN INGLES SIN PROBLEMA ..Y EN SPANISH SERIA PERFECTO.
my battery died and had to be replaced. evap sensor is incomplete. what do i have to focus on...im a total newbie do i have to do cold start each time?
Drove my 2001 Suburban today and cleared everything but the “Oxygen Sensor Heater” and “Evap System Monitor.” Do i just have to do step 1 & 2 and not worry about driving it for the other steps?
Just focus on the cold start steps for the o2 heater monitor. These monitor normally sets pretty fast.. Make your connections on the up stream sensor is clean and the battery is strong. A weak battery may prevent this o2 heater monitor from setting.
Shaun the evap is exempt even in California and there is not much you can do other than maintaining the fuel level of 1/4 to3/4 and parking on a flat surface.
Here is the toyota drive cycle ua-cam.com/video/EKfEr2LP2Nw/v-deo.html Make you vehicle battery is setting over 12 bolts in the morning before starting as low or less thank perfect battery can keep the o2 monitor from setting. If by the 3rd drive it’s not ready try check all the o2 connections.
Hello, thank you for all of the great information. I have an interesting situation on my 2014 Corvette. All of my monitors (including the evap) are in ready mode, except the EGR monitor. this monitor will not go into ready mode. I have driven the car 900 miles, and this one monitor will not set. The dealer has informed me to continue to drive the vehicle, as they cannot assist with any repairs. Any advice you can offer would be appreciated. Thank you...Rick
@@RANDOMFIX Hello, No mods on the exhaust, bone stock and BAR shows that it passed in 2020. I did change the steering wheel to an LED that plugs into the OBD port if that matters
@@RANDOMFIX Hello, the steering wheel only get power from the harness behind the airbag. the system is Bluetooth from the obd to the steering wheel. Thank you
Sorry, I forgot to mention it is an AT and there is no real link to the steering wheel, just an LED carbon fiber wheel. The wheel has LEDs built into the wheel. I recently disconnected all of the Bluetooth so the only thing hooked up is the steering wheel Power wire to the steering wheel harness behind the air bag. Thanks
2002 LS1 5.7L V8. Is there a way to skip some of the procedure if the only problem showing is that the CAT is incomplete? Put another way, what must I do to clear IM cat_inc (catalyst incomplete) flag? The O2 incomplete flag is not on. Please explain for a slightly slow four-year-old (or 75-year-old me). I have been going crazy driving and coasting, and going broke buying gasoline.
This is avery complicated topic, if your cat monitor is inc you should focus on higher speed driving for long durations and at 19 years old you catalyst maybe marginal and so comes the fun part of driving hundreds of miles to set the monitor. There a few products that can help but the only rear solutions is a new catalyst. Good luck and keep me the loop. I have a trick for older cars, you will find it one the smog tips playlist.
@@RANDOMFIX I still don't understand about drive-cycle. At what point am I wasting my time if I do not let it cool overnight? Is it even necessary to do the cold start if the only problem appears to be CAT_INC? In short, what exactly should I do? HELP! 🤪🤯😱
I have a have a video about it one the smog tips play list. You don't need to cool down if you are only to set the cat monitor. High speed driving at constant speed. No ac or cruise control.
I like your videos, but on a drive test, you do not discuss stop signs, red light leaving the house, and on the way to the highway. Does this matter? Does the 55 moh test portion start once you get to the highway, and do you recommend staying under 55 on the way. Keeping in mind the stop signs and lights we encounter on the way. Thank you
Thank yo for the feedback. The high speed starts once you get to that speed. I know it hard to do with traffic but do your best and then focus only unset monitors. After 2 cycles You don’t need to do it order for specific monitors. Keep me in the loop and good luck.
I have a 2001 Astro Van with about 65K miles on it. Cat, Evap, and EGR are not passed. I have done the Drive Cycle at least 20 times. When I started, the 02 Sensor and O2 Sensor heater were also not passed, but they went to OK after 4 or 5 drive cycles. I do have 2 issues with the Astro that may be causing the problem. The first is that the AC is not working due to a leak. The second is that the Fuel Level Sensor has an issue in that it becomes less accurate at about half of a tank. Any help would be appreciated as the Van runs great otherwise.
Also, just because your miles are low doesn’t not mean much as to condition of the vehicle. Do you drive it much? Watch this video and you will see what I mean ua-cam.com/video/Yn1-ul62Jio/v-deo.html Most importantly what caused this issue?
2000 4.3 silverado no check engine light and cat wont set. I do a drive cycle once every moring on the cold start and go 55 for 5+ min done it 2 times and still hasnt cleared any help?
I replaced all 4 o2 sensors on my hummer h2 and have been driving for a while but no luck the o2 still not ready no codes !! could ir be that there is something wrong or just need to keep driving ? i've been struggling for months
I would not continue to drive unless you have not done a proper warm cycle. So just start the hummer and let idle for over 15 minutes, make sure not to move or touch the gas pedal. If that doesn't work I would seek professional assistant. Is the ho2 the monitor that not set?
My 97 buick lesabre 02 sensor heater won't complete. Can I just keep doing the cold start idle with ac and rear defroster on, or do I need to do the driving part too?
All monitors are complete except the 02 sensor htr and evap monitor. They will pass you if the evap is not complete, so the 02 sensor htr is the only thing keeping me from passing.
did the drive cycle on my 2005 Cadillac and after driving 55 and using the emergency brake to slow down the dash display wont work, speedometer dead, odometer dead, turn signals dead, what the heck happened ?????
Sorry I never heard on such an issue occurring, did you resolve it? Please keep me posted as I would like to know possible causes. Gm is not known for great electronics but it sounds like a ground issue. I’ve had to rebuilt many gm clusters of the years.
I live in California. Have a new 2021 XT5 that I purchased in Arizona, O2 Sensor is still not ready even after driving 600 miles. CA DMV requires a smog on my vehicle. What can I possibly do to get this freakin O2 sensor to start working. Any and all feedback would greatly be a-predicated.
The creator, I have a 08 Chevy HHR, failed due to monitor not ready, EVAP, 02S, HRT.. now EVAP is ready but not 02S, HRT. But I note you say key out ignition.. the key stays in all night so prior to any cold start key is in. Is this why them two will not go ready? I put new battery in before putting up for sale, getting smog here in Cali I was made aware of the not ready. So failed test due to not ready. The EVAP was 2weeks to be ready. But as of right this minute 02S, HRT is still unready. So pulling the key for the over night cool down, then doing cold start will get these two unready to go ready?? I have no check codes and no repair needed. Just need to get 02S, and HRT to go ready..
Cold start in the morning and just let vehicle idle for a long time ( 20 minutes). You need to get that 02 heater monitor ready first and then focus the o2 monitor. Please check all your grounds and if this does not work, check o2 sensor connections to ensure everything is clean and nice tight. Keep me in the loop. Why did the inspection monitor data get deleted in the first place?
@@RANDOMFIX the battery was bad and hot cable, replaced both then new plugs and cleaned throttle body. Car running very good but them two are not ready still. I will try it again tonight, today I will check all wires an connections, I will keep you informed on it, thank you
Got it, just focus on that the long warm up. There is a product that I use for catalyst and it's suppose to help with o2 sensor but it would do any good if the connection is got good. If you get access to that o2 sensor, it's pretty easy to access on the hhr, disconnect the connection ( engine off) and make sure all is clean. The o2 heater is built into the upstream O2 sensor so the one before the catalytic converter.
@@RANDOMFIX ok, I'll do that now and after tomorrow morning warm up I'll check on readiness.. I have been watching on the scanner live streaming and the voltage is consistent with no drops or spikes, I will let you know after tomorrow morning warm up..
@@RANDOMFIX alright.. I had spoke on my Chevrolet hhr not going IM ready. Well it was close to a month and I had gave up on it, so just for shits and grins I connected the scanner, IM READY. So the event happened but not sure when. But rechecking and it's still clear no codes and IM ready.. so I guess from what I've been told is these HHR are funny with certain things, another haunting is tire pressure on dash will go --. --. And remote start will drop off.. this one still good but hopefully anything else will wait till I no longer have it.
The evap is exempt in most places except Oregon as far as I know and here is the video to help with your o2 monitor not setting ua-cam.com/video/Yn1-ul62Jio/v-deo.html Let me know what happens
I have all mine set to ready except evap and egr,I tried the driving and 65mph and slowing down with the break but I did down shift (I have a manual) is this the reason why it didn't work?
For the egr try coasting to under 20 Moh once you reach 65 Mph. The evap is a more complicated as I covered that in video. Keep you fuel between 1/4 to 3/4 and park on a level surface. Park for a least 8 hours and check to see if the evap is exempt in your state.
Hi, please focus on the o2 sensor monitor by performing proper warm cycles and low speed driving with a steady foot. As to the evap keep your gas level over a 1/4 and under 3/4, park on a level surface. The evap is not really required in most states and is even exempt is California. Keep me in the loop. If you have easy access to the o2 sensors please clean the contacts on the connection plug.
It's insane the government doesn't allow a way for citizens to safely self complete these checks. Like what do I do? Risk driving around 2 weeks till I can get a inspection? Tf?
i have bmw x5 2005 model and i have C and OH only not ready.. can i just do partial drive cycle that addresses C and OH to get them ready or do i need to do all steps.. The deaccelerating to less than 20 mph is the worst part and C or OH doesn't need this so wanted to skip..
Yes just focus on the unset monitors. I would try the drive cycle twice and the third cycle focus on a really long warmup for 25 minutes and then hit the freeway, keep your rpm below 3k so don’t go too fast. Keep me posted
@@RANDOMFIX I went on a long drive on Highway and tried to maintain 55-65 mph almost 50 miles and the Catalyst is set. Now waiting on the OH only, not sure why this one is still not ready. Keep driving ?
Here is the Bmw drive cycle m, please watch as it’s better than driving around for hundreds of miles ua-cam.com/video/mk6Tk330Acw/v-deo.html Let me know what happens
@@RANDOMFIX Thanks for the reply. I have 2 questions on the BMW drive cycle in the video link you sent. Step 2 says Idle - In Gear (Drive) - a.) is that normal idle or I depress brake and put the car in Drive for 2.5 mins while turning on Rear Defroster and Full on AC ? b.) Since i need OH heated oxygen sensor to be ON, Just step 2 is fine or i need to do the complete drive cycle ? Please clarify. much appreciated thanks
These drive cycles are insane we should be given access to a private track to complete all these procedures.
mine did it within two days basic driving didnt have to do any extra steps.. just drove to the store, got gas, some food, came home in less than 15 miles all were good to go except evap... next day went to work came home evap was good to go.. all within 25 miles and didnt even get on the highway
@@KrGsMrNKusinagi0 300 miles and the testing facility says mine isn't ready. My scanner says everything is fine, or rather 2 scanners say everything is as should be. Wonder why?
On my 99 tahoe, 420 miles and the evap is still incomplete, did all the drive cycle, drove in town, hwy over a 4 weeks period. Now need to wait for appointment at dmv to get another moving permit....
@@Loiczzr Mine passed well over 400 miles later. What a joke.
@@larryspiller6633 yeah it's crazy..
2021 Chevy Traverse passed after watching this video! Drove 800 miles , gas and nothing smh. Was about to give up. did this to the Tee! Less than an hour Greatly appreciate you !
Thank you for sharing your experience for your 2021 Chevrolet Traverse. Much appreciated
I did this drive cycle this morning after driving all day with three of my sensors not ready. After doing the drive cycle, the final two sensors turned ready and I can have my inspection the following day. I appreciate the walkthrough and explanation.
For me, the success of the drive cycle was the upon cold startup, turning on the defroster, AC…anything that can put as much electrical load on the system as possible. I didn’t do this prior and it made for a long day.
Also it is truly best to do the drive cycle early in the morning or late at night, preferably on the weekend as it’s when a lot of people sleep in. It made for a lot less concern and anxiety if you can only do this on a road that is often traveled at 65 mph minimum.
Thank you for your feedback, much apprecated!
5 STARS!!!! Thorough information, perfect!!!! Thank You...
Glad to help with your gm
Smog. Welcome to the channel.
Gm, here in Ohio. Thank you very much for the information. I have a Chevy Malibu that failed emissions 3x and I followed the drive cycle as instructed. Once going to another emission location, I was able to pass the test. Again, thanks!
Stanford, I'm glad to the video was helpful on your Chevrolet Malibu smog and it help you pass. I really appreciate you taking the time to post this. Thank you
Thank you! I just passed my smog (Class C motorhome on a 2000 Chevy Express chassis with the 7.4 liter V8). This video helped me get ALL my monitors ready (even the Evap System) in one trip, without a lot of gasoline expense and extra stress. Thanks again!
Glad to help with your smog test on your class c motor home. Thank you so much for the taking to time to share your story.
I finally got the drive cycle completed for my 2016 Chevy Tahoe. Great instructions. Just a couple things I had to do differently.
My O2 sensor would not set while I was trying to performing my drive cycle. I was about to give up and parked, let the car idle for a few minutes with the air and defrost on and turned off the vehicle. I waited a few minutes and started driving at 55mph for 3 minutes with no aie or defrost and it set.
Each time I allowed the car to coast below 20mph, I pressed the brakes before I started the next step in the drive cycle. (Before when I didn't hit the brakes below 20mph, it would not set)
I also purchased the ob2 reader you recommended and it's so much easier I don't have to manually hitting the buttons and keep checking the meter.
Thank for sharing your success on your 2016 Chevy, yeah the extra load from the air conditioning and rear defrost really helps with o2 monitor. This o2 trick is used mostly on honda but I’m see success with on all makes and models. Thank you again for taking the time to post your experience.
This video is outstanding. Had recent repairs to my chevy silverado 2500hd and was due for smog here in Cali. The smog place wanted me to drive 200+miles over the course of 15 drive cycles to get all the systems set. Found this video and got almost all sensors done in less than an hour. The only one sensor that hasn't set is the O2 sensor heater. Will try a cold start again once it's ready. Thank you for making this video!
Glad to help, make sure you battery is perfect if the if experience the o2 monitor not setting. Thanks again for the great feedback
@@RANDOMFIX yes sir. Two brand new batteries (it's a diesel), clean terminals, tight connection.
Yeah try that cold start and let idle for 20 minutes and go drive around town for 10 minutes.
My trouble is getting the CAT monitor ready. So difficult!
You're a genius! Thanks so much for this video. I drove around for a few hours trying to get the o2 sensor heater monitor ready. This morning I started my '99 Suburban; turned on the A/C, rear defrost, headlights and the o2 sensor heater monitor was ready in just under 2 minutes!
Liked, subscribed and "Super Thanks"ed (from my other Google account)👍
Glad to help and thank your for the feedback and congrats on getting your 99 Burban smog monitors ready.
You did a lot of work here to deliver some essential information -- much appreciated. I am learning the hard way, DIY ain't what it use to be. When I started working on my cars, who would of thought a technician degree would be a requirement for a tune up. Thanks again.
When you told me that your now gonna show me how to do the drive cycle, I literally thought you were now gonna show me how to do the drive cycle!
Lol, here I will show to complete the drive cycle ua-cam.com/video/jldTJI64cfM/v-deo.html
Please note that your vehicle drive is a little different from I show because you are driving a gm.
Good luck!👍🍀
VERY GOOD INFORMATION I PASSED MY SMOG THANKS
Glad to help
Thank you for this video! I only wish I would have found it before I wasted $80 on gas driving around aimlessly trying to ready the o2 sensor heater monitor. 🤬🤣
Have a awesome day and keep up the great work!
Glad to help and thank you for the support. The heater monitor should run first and should set really fast on your Chevy. I made an update to the o2 sensor video ua-cam.com/video/Yn1-ul62Jio/v-deo.htmlsi=6HmUbXote9z6VemE
Thanks again
How did you get rid of the o2 sensor heater?
Awesome information! I've been trying to get my EVAP to set to smog the truck and this gave me the directions to get it set. Thank you!
Glad to help and keep me posted about your evap.
It finally set the EVAP, after 2 run cycles I went to start it to do another run cycle and checked scanner and the EVAP was set. Thanks again!@@RANDOMFIX
Congrats on setting the evap and thank you for the update!!
What stepts did you do ? My evap isnt ready and thats all i need left
In California they allow the evap not to be completed. But if you had a previous evap code you repaired and cleared all DTC’s it still stores in the I/M trouble codes as a permanent code until the evap monitor has completed and no DTC is set to verify repairs have been made. They will fail you even if there’s nothing wrong with the vehicle and you have no codes present.
Yes you are right but there is still a way around as the the allow for the 15/200 rule.
I explain in in this video ua-cam.com/video/wcCRN_c6Mss/v-deo.htmlsi=CA7MXfPC5LLuf2J2
It’s very easy to meet this criteria. Thanks for sharing
@@RANDOMFIX failed me out right today due to a “ permanent code” for a fuel pressure sensor that I just replaced. Went to BAR’s website today and found out the cause is because permanent codes cannot be cleared manually only the ECM can clear them once the monitor is completed and it verifies the repair has been completed. I don’t smog cars anymore it’s been some time and apparently this is a new thing started in 2019 affecting vehicles from 2011 and newer. BAR states it’s a issue they are currently working on with the state of California because it’s causing some issues. From what I see it wasn’t the shop that failed me it was automated by the smog machine. I just watched your video about the 15/200 rule, I did read that on BAR’s website as well. Thank you for your reply and your videos
Thanks it worked for my 2019 chevy malibu. Failed emission twice after following your instructions it passed. My mechanic put me in the right direction to look into drive cycle.
Thank you. Ps issue was due to me disconnecting battery because. I had a p1101 fault, I did resolve the code issue first.

Dear Sir,
This video has provided me with remarkable amount of knowledge of the smog process. Fantastic information.
I have a problem with the procedure for a 2017 Chevrolet SS Sedan. Battery was replaced and the dealer Cleared all codes and has been unable to get this car to pass smog.
Any specific data to support GM ODB2 driving cycle reset procedure 2017 Chevrolet ss Sedan.
Please advise.
Complete two drive cycles on your ss sedan and then focus on the unset monitors. I show the drive cycle on this video ua-cam.com/video/jldTJI64cfM/v-deo.htmlsi=MbtICN8aQnCVk8MC
This is a general drive cycle and should work for your Chevy as it’s less than 10 years old.
I will follow instructions and report Back
Great video, very informative.
Glad to help let me know if you run into any issues with your gm vehicle.
thank you,very informative
Robert, glad to help. Thank you so much for positive feedback
Thanks for the info 😊
Glad to help.
Thanks. Really helpful.
Thank you foe the information
@RANDOMFIX Thanks you the easy to follow steps. I had to change out my battery, and could not figure out how to get this aggravating thing ready. One thing, I assume these test do not have to be run together. I live in the city, and it is hard to find a place I can run 55 mph 3 to 5 minutes straight. So, I'll have to drive to different highways to get them all done.
Had a catalyst monitor that wouldn't set (2007 Tahoe) but your video info worked in just 45 minutes. BUT, I then stopped and filled the gas tank, upon leaving the DIC started saying over and over that the stabilizer system was off, so, I then stopped and shut off the engine and the stabilizer thing went away but now have 4 monitors that are not set including the catalyst one. Maybe a ground? I am at a loss.
Yeah I have heard of monitor information getting lost after each turn off so yes it could be a ground. The question is if you set a monitor now and turn off the vehicle will it lose the monitor data again?
@@RANDOMFIX Right, I need this vehicle, so I am cleaning up all the grounds I can find, and adding a few to any ground wire I can find. It was a Michigan car, now Arizona, has rust and corrosion in places. Adding grounds body to frame, body to engine. I assume the main ECU is the fault because there are several different types of monitors that now need setting. So I will try to find a wiring diagram and try to re-ground it, the OBD2 port did not work at first, so I unplugged then replugged in the big cable bundle connectors on the ECU and now it works. I have since blown it out with air and replugged it several times to kind of clean the terminals on the connectors. Any advice would be helpful.
Great video
Good to hear the video was helpful with your gm smog
For me I kept having an issue where my 09 Denali wouldn't run the readiness test for the catalyst monitor for like a week, turned out I was not letting it get hot enough from a cold start. I let it warm to 190 one day after work and luckily I can hit about 50+ miles an hour as soon as I pull out of the parking lot and it readied all test minus the Evap and the drive wasn't even over 5 minutes long.
Thank you for sharing your experience on your 2009 Denali
Your like 👍 and a new subscriber thank you for the knowledge sir
I appreciate your constructive comments, thank you for the feedback!
I agree .and some of the instructions i cant do correctly cuz i cant get up to speed untill i leave town.. then theres finding a roads without bends that require breaking to reach a safe speed.decellerating is unsafe cuz you cant warn drivers behind you without using breaks. I find it frustrating to say the least.
Just do your best and after two attempts focus only the unset monitors. Let me know what your are struggling with?
Man I got 2014 Chevy Silverado been driving around for 3 days 400 miles can se to set I do 1 cold start but still have 3 monitors on I’m keep doing hopefully we get this cleared up 😂
What monitors are still incomplete and what caused this issue to begin with?
Catalyst hasnt set after following drive cycles. O2 sensors im readiness shows ready. Still think I should follow o2 sensors? 167 miles since codes reset.
If the catalyst is the only monitor left than start the vehicle with air conditioning running and a full extricate load and after 20 minutes take your vehicle on the freeway and get that catalytic converter nice and hot. Hill and mountain will help heat it up. Don’t drive with air conditioning or cruise control
Good luck and keep me posted
I have a 2013 Chevy Cruze the o2 sensor monitor is still incomplete. And I can’t run my AC as it needs to be fixed, will my o2 sensor not complete until ac is fixed ?
Sorry for the late reply, I appreciate your feedback
did you get this handled?
also Isuzu has a GM 360 called Isuzu Ascender just a rebranded TrailBlazer and SAAB 9x7 also a rebrand TB..
Thanks for the video. I have a 2007 Sub with only 74 miles. Check engine light turned on with OBD code P0446 (Evaporative Emission System Vent Control Circuit 1/1. I've replaced the gas cap, vapor vent canister valve, vapor jumper wire and the Emissions Vapor Canister Purge Valve Solenoid EVAP Vent ( I don't think it's necessary but I did it anyway). Cleared it and the check engine light is gone but after driving 93 miles, the I/M is still not ready with a combo drive of city and fwy. Drove it for another mile and after 6 cycles, when I ran the OBD at 94 miles to see if it's I/M ready, unfortunately I see the same "pending" P0446 code despite driving it up to 110 miles hoping it will clear on it's own. So I decided to erase the pending code/OBD and did the same thing again. Drove it up to 92 miles without check engine, still not I/M ready and at 94 miles later it's still not ready and the "pending" p0446 code is back. Replaced the vapor vent canister valve, vapor jumper wire again just in case I have a bad part, but unfortunately pending P0446 code is back. I'm hesitating on replacing the vapor canister/charcoal cause I don't have an issue filling up gas and no gas odor around the area too. Could it be the another bad vent valve? fuel tank pressure solenoid? I hope not... cause I know this is pretty common on the 2006 but not on the 2007.
Cleared it for the 3rd and 4th time, gas level is between 3/4 or 1/2 and the pending code is on after 10 miles but still not I/M ready. Should I just keep going and repeat the drive cycle until it clears or do I need to change the ftp and the V.C. Charcoal too? I'd really appreciate yours suggestion cause I need to pass smog. One last question below;
I heard I can pass with a pending code as long as no check engine light is lit. But can I pass smog with 1 pending code and evap not ready but everything else are?
Yes, you should be good with no check engine light and evap monitor that not ready even if you have pending code. Don't wait too long as the code might trigger the check engine light. If they technician checks with the cheap little scanner before he smogs he may turn you away because he doesn't want it to count against his passing data or stats so then go to another station. I know it's annoying and a waste of time!!!!
@@RANDOMFIX Whoa! Thanks for the quick reply. Unfortunately I reset it by accident, so now I have to drive it around again to get it ready.
man, I can't even pass the emission because the EVAP in incomplete mode.. I drove 110 miles yesterday and nothing changed and now i used to scanner this morning and i accidently hit reset and now the whole smog tests are incomplete ..AHHHH i have appointment with the DMV this monday and i won't be able to get emission test to pass..
The evap is most likely except. Even in California.
Need help I put a new cat on my 2009 Chevy Tahoe cleared the cat and o2 sensor but the o2 heat is still incomplete any suggestions on how to my it ok??
Yes, this is common and I made a video about it
ua-cam.com/video/Yn1-ul62Jio/v-deo.htmlsi=lCJAv8xvrIQ8kPQL
Keep me posted
what should i do if i live a 10 min drive to the highway , with lots of traffic lights in between here and there? will it affect my drive cycle to do the cold start, ac running, and then drive in a stop and go manner until i can get to 55mph?
Just for your best or wait for off peak hours. If it effects the drive cycle you can just repeat that part of process.
Brother nice video, I only have o2’s and HRT monitors not ready, I could just do the cold start and turn on cold AC and rear window defroster and it should activate right?
Yes and make sure you battery is perfect l, you will need check the battery voltages with the car off after running the headlights for a few minutes to get rid of any surface charger. If that if still doesn’t set check the connectors while the vehicle is off and verify is everything is solid and clean.
I got all the im readiness except the o2 heater monitor. Im surprised i got the EVAP ready before the htr . Any ideas?
Yes, I covered that in this video ua-cam.com/video/Yn1-ul62Jio/v-deo.html
All codes cleared. Did the drive cycle in my 2000 S10 V6. Left a comment in another video that you just answered. I only have to get the HTR to set. You said it is the first thing in the drive cycle. Does it set if it is ok after cold start and idle for 2.5 minutes. How far throught the drive cycle do I have to go? I hope not all the way. It seems it will know how long it takes to from open loop to closed loop pretty early on in the test.
It should be one of the first monitors to set. I would check the heater element if it doesn’t get ready soon. It’s easy to do. Just focus on the warm up.
ua-cam.com/video/sAvxeAyYsRk/v-deo.html
@@RANDOMFIX It set this morning. Warmed it for 3 minutes, drove around the neighborhood until it came up to temp. Came home, hooked up the scanner and all monitors are set except the EVA and that one does not need to be set in order to pass. So my guess is the o2 sensor heater is something that needs several cold starts before it will set. In my case there were 4. Or maybe the heater is just weak. IDK. But it's all good and I am very happy about that.
Thank you for your time.
Thank you so much for the update and congrats on getting the htr monitor ready. Much appreciated
How does one get the AIR pump ready. Mine simply refuses to be ready. Is it ONLY cold starts or does that monitor require drive cycles? It’s the only monitor I’m concerned with.
Sorry for the late reply! did you find a solution?
Wow, four air pump, but I am glad to hear the issue got resolved.
Of course i had a check engine light day of smog for a fuel level circuit code cleared the code got all monitors ready except heated oxygen sensor 2009 chevy tahoe how do i ready that one
For the heated o2 just let it ideally normally it’s one of the first monitors to set. This explain a little more in depth. Is the front (pre cat) o2 sensor the original sensor that the Tahoe came with? Has it ever been changed?
ua-cam.com/video/Yn1-ul62Jio/v-deo.htmlsi=3EucTwQ1eSaG_dCw
@RANDOMFIX all monitors were ready/ok i had a check engine light on so fixed the light and tried to ready monitors its only been 1 day.. so ill try again today thanks
So I live 2 mins from the freeway should I do the first part of the drive cycle in my driveway or should I start the truck and get near the freeway then start the drive cycle? Thanks in advance 👍
You don't need to turn off the vehicle. Just follow the directions best you and then focus on only unset monitors
That’s my question, does it have to be in order or can I cold start and drive to a freeway after 3 min?
hello I have a Suburban 99 it is time to renew the registration for which I need the smog and after disconnecting the battery for a long time since it is a vehicle that is driven very little and when reconnecting the battery and driving it approximately 200 miles the HTR O2 sensor monitor is the only one that is not complete, I am thinking that it could be the oxygen sensors that are already old?
Sorry for the late reply! did you find a solution?
Will this work on my 08 silverado lt 1500 5.3 extended cab? Been trying this for a while but no luck getting frustrated

Can you refer me to a good video on the Toyota drive cycle?
Sure ua-cam.com/video/EKfEr2LP2Nw/v-deo.htmlsi=AQhGC6V7trK-vDQX
Does it have to be 55 mph? Can I drive at for example 65-70 mph? I don't think it is a good idea to drive at 55 mph on the highway.
Sorry for the late reply! did you find a solution?
Another add to get power moving is turning the steering wheel causing the power steering to work
Thanks for the feedback
Thank you. Very helpful. I tried this several times, over the course of several days, but Cat and EVAP is still not setting. All others are set. Not sure if I am missing something. Do I have to start the whole new cycle from cold if I am just trying to get Cat monitor to set or can I just focus on the Cat setting procedure?
Daniel focus on just the catalyst so drive at freeway speeds for long durations. What is the make, year, and model of the vehicle?
@006pup 55 to 60 drive then coast to under 20. Do it a few times n you should be good. Scan tool helps. I leave mine hooked up and I look over occasionally
Same issue for 2013 sierra 2500hd diesel, catalyst and o2 heater sensor... I'm about to give up
Focus a proper warm up. Check all the connections on the oxygen, the precat 02 sensor. Look the connectors and make sure they are clean and snug. After your o2 heater sets then your catalyst will set.
Also, up to 2 monitors can be exempt on diesel including the catalyst, for gas only the evap is exempt. I hope that is helpful and keep me in the look.
Great video bro! Any advise for me? I have a 2001 Silverado and just did an engine rebuild. No codes and and monitors passed except the Secondary Air System. It says Not Ready. I have already put 900 miles on the new engine. Anything you can recommend?
I hate these chevys and gms they make it way too difficult
Focus on the those cold starts when the secondary air system kicks in. Also, check all the connections on your rebuild.
You have alot of great videos can you direct me i have a 2004 chey silverado and im getting a p1035 any ideas
I think you are just coping and pasting this question as I just answered it on my actual drive cycle video.
I did ask on another video
This is by far the best video I've seen to run the drive cycle.Accurate and carefully explained on a state to state basis.5 STARS!
Kat, thank you for the great feedback. Much appreciated
2001 s10 2.2L secondary air system monitor does not want to set ive been doing cold starts for the past 2 weeks and nothing no codes no pending faults i changed the check valve etc and still nothing
Does the secondary air system engage when the vehicle first starts while it’s cold?
Could you please tell me what i need to do to get the “HTR” monitors ready? All other monitors are said as ready or N/A 2002 chevy suburban 1500 5.3l v8
This is o2 heater monitor sheikh normally sets first. I would try a few more times but I have seen a lot of these 2000+ hm product act up when the battery is not perfect. I covered this in my last 02 video from last month. ua-cam.com/video/Yn1-ul62Jio/v-deo.html
The heater element is inside the the o2 sensor ( upstream ). If the video does not help clarify try testing it
ua-cam.com/video/zEbXn6vgqiA/v-deo.html
I think it will pass heater test but it could aged. Incase you replace make sure you use an oem sensor.
Good luck and keep me in the loop.
Anyone know the exact steps for the evap to be ready … thats the only one im having issue with
You don't need it to be ready in any state. It will pass witout it being ready.
I have a 2003 chevy silverado, the only incomplete monitors I currently have are the catalyst and evap monitor. Can I skip the other steps and go straight to the steps to get the catalyst monitor to complete?
Yes, and the longer you let vehicle idle and warm up the easier it will be set catalyst monitor. The evap is exempt so focus only the catalyst
If you have low power steering fluid do you need a scaner to my the check engine light go out
The check engine light is not normally triggered by an older power steering system. Maybe on of the newer electric powering steering system may trigger a cel. I would recommend buying a cheap 30 dollar tool. There is a link the video description
What are you doing to set warm up cycles? I have a permanent on and need to do 15 warm up cycles
Warm up cycles and then drive around town for 10 to minutes.
Great video! BUT, I can't get my 2000 c3500 7.4l to pass the egr check. I haven't driven the truck in over 2 months, So when I had to jump start the battery my emissions reset. Of course now I have to get a smog test. Do I need to go through a complete drive cycle or can I just focus on one set of parameters to get the EGR test to complete? No mods or anything like that. Thank you in advance and your expertise
Thanks for the feedback, much appreciated, just focus on the egr however make sure your battery is good by using a load tester and not just by checking the surface charge voltage. I would coast from 65 to 1 to 2 mph without using the brake pedal. So find a nice open road and coast. Do this 3 to 4 time recheck the egr monitor. Keep me the loop.
Thank you for the reply. I tried that and drive around over 100 miles. Found areas where I could get to speed and slowly coast. Unfortunately, it didn't work!
Absolutely great video man new subscriber! Couple of questions though. In California 1999 cars are allowed 1 incomplete monitor and the evap is exempt. So if evap monitor isn’t ready and also another monitor isn’t ready does that count as just 1 monitor not ready you think? Or it’s 2 and it’s a fail?
It's considered 2 and a fail
Yes you are correct about this!
Hi can you use the cruise control when holding speed on the highway?
Some monitors won’t run if cruise control is engaged.
1997 gmc safari n everything is good but I get the PO420 code ?? 19:32
you will need to stop getting that 420 code from being detected before your start your drive cycle. The Permanent solution is to replace the catalyst but that can be expensive. In case the code doesn't pop up right away I would try some of the temporary solution I show here ua-cam.com/video/BuZYAy_xi0E/v-deo.html
Good luck and keep me posted on your 1997 GMC safari.
Did this 2 times on a Chevy Malibu 2006. It didn't pass smog. It missing the CAT to pass. The CAT is new just had it replaced.

INSPECTION/MAINTENANCE COMPLETE SYSTEM SET PROCEDURE
DIAGNOSTIC INSTRUCTIONS
Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure.
Review Strategy Based Diagnosis for an overview of the diagnostic approach.
Diagnostic Procedure Instructions provides an overview of each diagnostic category.
DESCRIPTION
The purpose of the Inspection/Maintenance Complete System Set Procedure is to satisfy the enable
criteria necessary to execute all of the I/M readiness diagnostics and complete the drive cycles for those
particular diagnostics. When all I/M monitored diagnostic tests are completed, the I/M System Status
indicators are set to YES. Perform the Inspection/Maintenance Complete System Set Procedure if any
I/M System Status indicators are set to NO.
Inspection/Maintenance Data List
To determine if the inspection/maintenance readiness diagnostic tests can be run this ignition cycle, use
a scan tool to observe the inspection/maintenance monitor enabled parameters in the
inspection/maintenance Data List.
CONDITIONS FOR MEETING A COLD START
The ignition voltage between 11-18 volts.
The barometric pressure is more than 75 kPa (10.73 PSI).
The start-up engine coolant temperature is between 4-30°C (39-86°F).
The start-up intake air temperature is between 4-30°C (39-86°F).
The difference between the IAT and the ECT is less than or equal to 6°C (10.8°F).
The ambient air temperature is between 4-30°C (39-86°F).
The fuel level is between 15-85 percent.
CIRCUIT/SYSTEM VERIFICATION
Review the inspection/maintenance system status indicators with a scan tool. All I/M system status
indicators should report YES, and no I/M Test DTCs should be present.
INSPECTION/MAINTENANCE SYSTEM SET PROCEDURE
NOTE: Whenever the ignition is turned ON, ignition positive voltage is supplied to the heated oxygen
sensor (HO2S) heaters. After verifying the enable criteria, turn OFF the ignition for approximately 5
minutes to allow the sensors to cool before continuing with the test. Once the engine is started, do
NOT turn the engine OFF for the remaining portion of the set procedure.
1. Ensure that the vehicle meets the conditions for a cold start listed above.

I appreciate your constructive comments, thank you for the feedback!
my battery died and had to be replaced. evap sensor is incomplete. what do i have to focus on...im a total newbie do i have to do cold start each time?
I didn't see your commeent before, do you still need help?
Drove my 2001 Suburban today and cleared everything but the “Oxygen Sensor Heater” and “Evap System Monitor.” Do i just have to do step 1 & 2 and not worry about driving it for the other steps?
Just focus on the cold start steps for the o2 heater monitor. These monitor normally sets pretty fast.. Make your connections on the up stream sensor is clean and the battery is strong. A weak battery may prevent this o2 heater monitor from setting.
Worry about the evap last as it may be exempt
how do I set off the evap monitor specifically for gm? I have a 2010 chevy equinox 4 cylinder I've driven over 380 miles lol
Shaun the evap is exempt even in California and there is not much you can do other than maintaining the fuel level of 1/4 to3/4 and parking on a flat surface.
2011 Toyota RAV4 catalyst and oxygen monitor not resetting to be ready after multiple times . Any suggestions for this vehicle
Here is the toyota drive cycle

Make you vehicle battery is setting over 12 bolts in the morning before starting as low or less thank perfect battery can keep the o2 monitor from setting. If by the 3rd drive it’s not ready try check all the o2 connections.
Hello, thank you for all of the great information. I have an interesting situation on my 2014 Corvette. All of my monitors (including the evap) are in ready mode, except the EGR monitor. this monitor will not go into ready mode. I have driven the car 900 miles, and this one monitor will not set. The dealer has informed me to continue to drive the vehicle, as they cannot assist with any repairs. Any advice you can offer would be appreciated. Thank you...Rick
Hi Rick, any mods on your 2014 vette?
@@RANDOMFIX Hello, No mods on the exhaust, bone stock and BAR shows that it passed in 2020. I did change the steering wheel to an LED that plugs into the OBD port if that matters
Hi Rick, does you steering wheel just get power from obd2 port? Can you send me a link to it. Also, is it an at or mt?
@@RANDOMFIX Hello, the steering wheel only get power from the harness behind the airbag. the system is Bluetooth from the obd to the steering wheel. Thank you
Sorry, I forgot to mention it is an AT and there is no real link to the steering wheel, just an LED carbon fiber wheel. The wheel has LEDs built into the wheel. I recently disconnected all of the Bluetooth so the only thing hooked up is the steering wheel
Power wire to the steering wheel harness behind the air bag. Thanks
I have to drive a short distance to a highway before going 55mph. Will this drive cycle still work ?
Yes, do you best and after two times focus only the unset monitors. I’m here for help
2002 LS1 5.7L V8. Is there a way to skip some of the procedure if the only problem showing is that the CAT is incomplete? Put another way, what must I do to clear IM cat_inc (catalyst incomplete) flag? The O2 incomplete flag is not on. Please explain for a slightly slow four-year-old (or 75-year-old me). I have been going crazy driving and coasting, and going broke buying gasoline.
This is avery complicated topic, if your cat monitor is inc you should focus on higher speed driving for long durations and at 19 years old you catalyst maybe marginal and so comes the fun part of driving hundreds of miles to set the monitor. There a few products that can help but the only rear solutions is a new catalyst. Good luck and keep me the loop. I have a trick for older cars, you will find it one the smog tips playlist.
@@RANDOMFIX How about a hint as to how to find the trick for older cars?
@@RANDOMFIX I still don't understand about drive-cycle. At what point am I wasting my time if I do not let it cool overnight? Is it even necessary to do the cold start if the only problem appears to be CAT_INC? In short, what exactly should I do? HELP! 🤪🤯😱
I have a have a video about it one the smog tips play list. You don't need to cool down if you are only to set the cat monitor. High speed driving at constant speed. No ac or cruise control.
I like your videos, but on a drive test, you do not discuss stop signs, red light leaving the house, and on the way to the highway. Does this matter? Does the 55 moh test portion start once you get to the highway, and do you recommend staying under 55 on the way. Keeping in mind the stop signs and lights we encounter on the way. Thank you
Thank yo for the feedback. The high speed starts once you get to that speed. I know it hard to do with traffic but do your best and then focus only unset monitors. After 2 cycles
You don’t need to do it order for specific monitors.
Keep me in the loop and good luck.
I have a 2001 Astro Van with about 65K miles on it. Cat, Evap, and EGR are not passed. I have done the Drive Cycle at least 20 times. When I started, the 02 Sensor and O2 Sensor heater were also not passed, but they went to OK after 4 or 5 drive cycles. I do have 2 issues with the Astro that may be causing the problem. The first is that the AC is not working due to a leak. The second is that the Fuel Level Sensor has an issue in that it becomes less accurate at about half of a tank. Any help would be appreciated as the Van runs great otherwise.
What caused this issue? The fuel level sensor may prevent certain monitors from setting.
Also, just because your miles are low doesn’t not mean much as to condition of the vehicle. Do you drive it much?
Watch this video and you will see what I mean ua-cam.com/video/Yn1-ul62Jio/v-deo.html
Most importantly what caused this issue?
Can you send me the list for the drive cycle? Please and thank you Like the video.
Hi Rose, I make a video for each make and did keep any list after making the video.
Thank you very much the video I just seen was very Informant
@roseharris456 glad to help and thank you for the kind feedback
2000 4.3 silverado no check engine light and cat wont set. I do a drive cycle once every moring on the cold start and go 55 for 5+ min done it 2 times and still hasnt cleared any help?
I didn't see your commeent before, do you still need help?
So my Evap is not ready… do you know if they will still pass me In the state of New Jersey with just that one off ?
In most states even California the evap is exempt. So you should be clear.
I replaced all 4 o2 sensors on my hummer h2 and have been driving for a while but no luck the o2 still not ready no codes !! could ir be that there is something wrong or just need to keep driving ? i've been struggling for months
I would not continue to drive unless you have not done a proper warm cycle. So just start the hummer and let idle for over 15 minutes, make sure not to move or touch the gas pedal. If that doesn't work I would seek professional assistant. Is the ho2 the monitor that not set?
I never had to do this to my 1974 Pontiac Ventura or my 1977 Chevrolet Impala now with this 2012 Impala like every 3 years this happens
Yeah, that’s why the 74 Ventura and 77 impala are worth more money. These newer vehicles are a pain in neck.
I drove the Silverado truck 2007 but I have 1 more monitor heater oxygen inc., it’s taking too long I drove 123miles at 55
I appreciate your constructive comments, thank you for the feedback!
My 97 buick lesabre 02 sensor heater won't complete. Can I just keep doing the cold start idle with ac and rear defroster on, or do I need to do the driving part too?
This is older than 2000 so you have have multiple monitors not ready. Let me know if you need additional information
All monitors are complete except the 02 sensor htr and evap monitor. They will pass you if the evap is not complete, so the 02 sensor htr is the only thing keeping me from passing.
Normally if it’s old than then 2000 they will pass it with two monitors incomplete. What state are you?
did the drive cycle on my 2005 Cadillac and after driving 55 and using the emergency brake to slow down the dash display wont work, speedometer dead, odometer dead, turn signals dead, what the heck happened ?????
Sorry I never heard on such an issue occurring, did you resolve it? Please keep me posted as I would like to know possible causes. Gm is not known for great electronics but it sounds like a ground issue. I’ve had to rebuilt many gm clusters of the years.

I live in California. Have a new 2021 XT5 that I purchased in Arizona, O2 Sensor is still not ready even after driving 600 miles. CA DMV requires a smog on my vehicle. What can I possibly do to get this freakin O2 sensor to start working. Any and all feedback would greatly be a-predicated.
Sorry for the late reply! did you find a solution?
The creator, I have a 08 Chevy HHR, failed due to monitor not ready, EVAP, 02S, HRT.. now EVAP is ready but not 02S, HRT. But I note you say key out ignition.. the key stays in all night so prior to any cold start key is in. Is this why them two will not go ready? I put new battery in before putting up for sale, getting smog here in Cali I was made aware of the not ready. So failed test due to not ready. The EVAP was 2weeks to be ready. But as of right this minute 02S, HRT is still unready. So pulling the key for the over night cool down, then doing cold start will get these two unready to go ready?? I have no check codes and no repair needed. Just need to get 02S, and HRT to go ready..
Cold start in the morning and just let vehicle idle for a long time ( 20 minutes). You need to get that 02 heater monitor ready first and then focus the o2 monitor. Please check all your grounds and if this does not work, check o2 sensor connections to ensure everything is clean and nice tight. Keep me in the loop. Why did the inspection monitor data get deleted in the first place?
@@RANDOMFIX the battery was bad and hot cable, replaced both then new plugs and cleaned throttle body. Car running very good but them two are not ready still. I will try it again tonight, today I will check all wires an connections, I will keep you informed on it, thank you
Got it, just focus on that the long warm up. There is a product that I use for catalyst and it's suppose to help with o2 sensor but it would do any good if the connection is got good. If you get access to that o2 sensor, it's pretty easy to access on the hhr, disconnect the connection ( engine off) and make sure all is clean. The o2 heater is built into the upstream O2 sensor so the one before the catalytic converter.
@@RANDOMFIX ok, I'll do that now and after tomorrow morning warm up I'll check on readiness.. I have been watching on the scanner live streaming and the voltage is consistent with no drops or spikes, I will let you know after tomorrow morning warm up..
@@RANDOMFIX alright.. I had spoke on my Chevrolet hhr not going IM ready. Well it was close to a month and I had gave up on it, so just for shits and grins I connected the scanner, IM READY. So the event happened but not sure when. But rechecking and it's still clear no codes and IM ready.. so I guess from what I've been told is these HHR are funny with certain things, another haunting is tire pressure on dash will go --. --. And remote start will drop off.. this one still good but hopefully anything else will wait till I no longer have it.
Does all this apply to a 2011 LML Duramax as well or is diesel different? Thanks
Sorry for the late reply! did you find a solution?
Everything gets ready except 02 monitor and evap after 5 drive cycles and 400 miles of driving, 05 Cadillac sts
The evap is exempt in most places except Oregon as far as I know and here is the video to help with your o2 monitor not setting ua-cam.com/video/Yn1-ul62Jio/v-deo.html

I'm getting a pending p0118 code on my 01 Buick century... I been driving but the tips had not working yet.. Any suggestions?

2000 gmc sierra 5.3 v8 Getting code p0420 and 430 with new o2, all 4, and both cats are brand new.... also new mass air plugs etc etc. Help me please
Really? I would reset it and see if it happens again. Are the 02 oem? This should not be happening if the catalyst is new.
I have egr and cat that won’t go off everything else is ok
What year is your vehicle? Have you made a recent repair?
I have all mine set to ready except evap and egr,I tried the driving and 65mph and slowing down with the break but I did down shift (I have a manual) is this the reason why it didn't work?
For the egr try coasting to under 20 Moh once you reach 65 Mph. The evap is a more complicated as I covered that in video. Keep you fuel between 1/4 to 3/4 and park on a level surface. Park for a least 8 hours and check to see if the evap is exempt in your state.
@@RANDOMFIX when I coast to under 20,do I put it in neutral or leave it in gear?
Leave it gear if possible but do not touch the brake.
@@RANDOMFIX thx,going to try again this weekend.
Will GM Engine light blink when not ready like Ford- Jeep- and Honda’s Do when you put the key in
James, As far I know GM does not have the a readiness check like the fords, jeep, or honda vehicles.
I got a jeep renegade. Im having issues trying to get an inspection due to obd smog readiness check not passing. So yeah it does have one.
I've been driving around for hours now. Just decided to look up videos instead of listeneding to the mechanic.
We know that the jeep has the readiness check but are you saying the gm has built easy to tell method to verify all the monitors are ready?
Good video , my truck is an 2001 Silverado 4.8 regular cab with no defroster and no a/c ! Is there any other trick to get heater monitor ready?
Thank you for your feedback, much apprecated!
Hi my 2012 GMC Terrain won’t complete EVAP and O2. All others are complete
Hi, please focus on the o2 sensor monitor by performing proper warm cycles and low speed driving with a steady foot. As to the evap keep your gas level over a 1/4 and under 3/4, park on a level surface. The evap is not really required in most states and is even exempt is California. Keep me in the loop. If you have easy access to the o2 sensors please clean the contacts on the connection plug.
It's insane the government doesn't allow a way for citizens to safely self complete these checks. Like what do I do? Risk driving around 2 weeks till I can get a inspection? Tf?
i have bmw x5 2005 model and i have C and OH only not ready.. can i just do partial drive cycle that addresses C and OH to get them ready or do i need to do all steps.. The deaccelerating to less than 20 mph is the worst part and C or OH doesn't need this so wanted to skip..
Yes just focus on the unset monitors. I would try the drive cycle twice and the third cycle focus on a really long warmup for 25 minutes and then hit the freeway, keep your rpm below 3k so don’t go too fast.
Keep me posted
@@RANDOMFIX I went on a long drive on Highway and tried to maintain 55-65 mph almost 50 miles and the Catalyst is set. Now waiting on the OH only, not sure why this one is still not ready. Keep driving ?

a.) is that normal idle or I depress brake and put the car in Drive for 2.5 mins while turning on Rear Defroster and Full on AC ?
b.) Since i need OH heated oxygen sensor to be ON, Just step 2 is fine or i need to do the complete drive cycle ?
Please clarify. much appreciated thanks
