The video that keeps on giving after 6 years! I just got a scanner with live data streaming (Thinkobd 100)and was going to look all this up, but, you did a fantastic job of covering it all. Thanks again.
I have the foxwell 301 and it says my brand new O2 sensor is bad. I found out I have oil leaking into the spark plug holes I got a new valve cover and gasket coming a new O2 sensor bank 1 upstream coming and have down stream for my Chevy Cruze how do you check the thermostat temperature on the OBD2 scan tool
I'm 21 and just bought one for my 97 licoln town car ss and I fixed my check engine light today lol I came here to better understand the ebd2 scanner and u helped thank you 🤝
I know Im asking randomly but does someone know a way to get back into an instagram account? I was stupid forgot the login password. I would love any help you can give me.
@Mauricio Brett Thanks so much for your reply. I found the site thru google and Im waiting for the hacking stuff now. Looks like it's gonna take quite some time so I will get back to you later with my results.
If you write a list that explains each acronym. You’re going to be love by so many people, since the scanner manual doesn’t come with it. And if you somehow provide that list, legend whatever you what to call it as a PDF. I promise a guarantee subscription and promotions of your channel from my part.
Great video 👍 FYI, for some of ur viewers: Bank 1 is driver side, Bank 2 is passenger side Sensor 1 is the sensor closest to the front, Sensor 2 is farther rear. Example: If O2B1S2 is bad, you don't need to replace them all. Just the one O2 sensor on the driver side behind the catalytic converter. (Sensor 1 is closer to the engine, if you follow the tube)
@@22mrwright Great observation. It probably is, but you would want to compare against the values for the other sensor on the same side, B1S1, and see if those fluctuate equally. If B1S1 also don't fluctuate as much, then it should be ok. Otherwise, I'd consider changing it as well. 👍
I have a P0171 code on my Volvo XC90. The ST and LT trim stays within range the entire time while checking live data, but the lean code still illuminates the check engine light. Wondering how this can be while in range. Also, smoke test revealed no leaks. Oil trap was replaced, new plugs too.
I just subs, good information and your one of the few that explains how to read a scanner. May I suggest using a tripod, it would make the video topnotch
I have a 2002 nissan sentra and the SHRTFTB1S2(%) and SHRTFTB2S2(%) stays at 99.2 all the time. Would that be bad sensars after the converter on both sides. Thanks for your help in advanced.
Thanks good, this really helped. My question is ,My Hyundai Elantra shows a stft bank 1 sensor 1 OK but it shows a bank 1 senso 2 frozen @ 99 % .Is there 2 of these sensors in a 4 cylinder engine or is that second one a dummy?
Hey, I'm just now seeing this. Thank you!! And yeah so you have an oxygen sensor before, and after the cat. That's why some cars have 4 02 sensors because the car has 2 cats, but that's mainly 6-8 cylinders with 2 banks. More often than not, an 02 sensor reading of 99% is cause by a bad sensor. It could also be wiring so just give that a look before replacing the sensor. I think I went over that in one of my later videos, but if not it will definitely be in the new one I'm posting tonight!
Dude I'm so trying to diy ALL my own mechanic work ,fixes and upgrades MYSELF and this helps a lot.tha.ks for the videos brother 💪 I have a question.. When I'm trying to record live data...it's asking me something about a trigger type..idk what THIS means and was scared to choose because I don't know if I could possibly do something bad using my scan tool to my vehicle 🤷🏼♂️🤦♂️
Thank you for this info! My long term fuel trim shows 30% or higher at all times. Can anyone clarify on what could be the problem for this higher number?
The scanner shows (in the video) SHRTFTB1S2(%) NA. I have the same reading on my OBD2 when doing a "live data" scan. I can't find an explanation for this ANYWHERE. Can ANYONE explain this or where I should start trouble-shooting? Is this an indication my downstream O2 sensor is fried? A wiring issue? I'm lost. Thank You for any input on this!
A want to know how to really understand how to read the data to determine if there is a bad could or bad O2 sensor or bad injector, could you help me with that
I got 2006 honda odyssey my trottle position its a 13.3 this number its considered normal or it is a vacuum leak my short fuel trim is 14.5 bank 1 , and 6.2 bank 2?
I have a cable throttle body on my '99 Honda Civic. My TPS is perfectly calibrated according to voltage (.49v-4.54v), but according to my TPS PID I'm at 9% throttle with the engine off or at idle. I've been chasing a high idle, and after much research, checking for vacuum leaks and parts swapping, I'm suspecting the TPS. I see your % is at zero, when at idle, and I'm assuming when it's shut off. Should all cable throttle body cars have a zero value, or is 9% the value it sends to receive the appropriate fuel for idle and iac system?
You've probably fixed your problem by now but I have a cable throttle on a Mitsubishi Lancer. My OBD2 shows zero throttle position at 780rpm idle.......nightmare these closed loop engine control systems.
TP% is 15.3 at cold start idle,,,, ill check again when i let the car warm up. But im also having trouble with my rpms. Its this weird thing where when i let off the gas, the rpm drops below one. Aroud 0-30 mph and will drop down to 1.5 or maybe 1 from 30-60 mph and 60+ is fine, my car also shifts way before the redline. Im talking about like around 2rpm or lets say im going 40mph and the car is going to shift, itll shift with the rpm around 2 of 2.5, but it will never go to the redline. Even when gunning it. Any help?
I have code p0171 lean bank 1 & P0171 lean bank 1 pending also right now. Scion tC 2006 - maf, air filter and oxygen sensor replaced. My reading (closed circuit) for my 02 sensor (Bank 1) reads at Volt output 0.740 to 8.00(v) My 02b1s1 says n/a? my EQ_RATB1S1 read at 1.002 with rpm at 2800-3000. in idle 02bs1s2 dopped to 0.015 (v) My shorttf1 after warm up in idle 2.6 longft1 is 32.1 Rpm 2800-300 shortft1 moves -3.9 to 1.6 Longft1 stays at about 24% I cant tell if there is a vac leak, 02 is bad, fuel injectors/spark plugs bad or fuel pump. From my readings I cant tell what they mean... vac leak, fuel pump or 02 sensor Any advice? Side note the last 2 days just started with idle issue, hesitant when I press on the gas pedal. My throttle reads at 18% which is where I believe it should be.
My TP on my 06 f150 is over 20% negative and my mass air flow drops negative 70...What can be causing this? Truck runs fine at idle but after driving for over 30mins it losing power and when you press the gas starts making a rattling noise until it goes back to idle then it goes away.
My 2005 Subaru Outback is showing a check engine light and also cruise control. Around the same time my brother in law was having the same issue with his 2006 Subaru. Online it looks like this is a common problem with lots of suggestions on what Could be wrong. I checked the temperature of the catalytic converter with an infrared thermometer and that seemed to be in an acceptable range. I checked my gas cap and that seemed loose, so I replaced that. I have been filling with premium gas. I bought an obj scanner and the code is p0420. Live data shows 02b1s1 - 2.788. O2b1s2 - .840. O2b2s1 - 2.765 O2b2s2 - .735. Do these numbers tell you anything?
Ashur deKelaita well monitoring misfires with scanners only give you a cylinder misfire count and let's you know how many times there is a miss. but I can definitely make a video on how to diagnose a misfire and how to pin point what cylinder it is if you don't have a scanner with those capabilities
Good2Boost would that be in the LIVE Data section or you mean just when you get an error code in the stored/pending section. I have my car in now getting new spark plugs and perhaps coils (hopefully no injector needed) for a cylinder 5 misfire, and just want a way to diagnose with more accuracy to make sure the problem is indeed solved, since I would only get the misfire when jumping on the throttle. But my car was also running rich in bank 1 so appreciate all the info on live data as pertains to Oxygen sensors and fuel trim figures. There are no figures in Live Data that records data for spark plugs and ignition correct?
Ashur deKelaita that kinda sounds like a ignition issues bad coil maybe. and as far as using the scanner if you have a higher end one you can see exactly what cylinder is misfiring even if the cel isn't on for a miss. but the cause of it is up to you to figure out so I will Def make a video on that to show you how I go about finding which cylinder and why
and also Alot of scanner don't have the misfire count in the live data unless it's a pretty high end scanner. I'll make the video sometime this weekend so check back for it.
New to doing my own repairs and I came across an obd scanner and no check engine lights and the truck is running good. But the scanner says shrtftb1s3 (%) .....99.2 Is that normal?
Hi have a question. Honda pilot 2003 3.5 just two sensors up and down. Bank 1 Rich. STFT S1 -27.3% STFT B1. S2. -27.3% steady on both. Oxigen Sensors output V ( B1 -S1 0.855 V (B1 -S2 0.035V How come if S1 is reporting a Rich Sensor 2 is reporting Lean.???? My problem is that pcm is taking fuel away From bank 1 to the point in which That bank is not working... If you disconnect those 3 coils from bank 1 They don't miss. But I you reconnect the bank and Do the same thing to #2 bank each cylinders Started missing if you disconnect all 3 Engine won't die. Pcm supplies supplies fuel to bank 1 And then they are running... This is weird !!! Then if you reconnect bank 2 Pcm shutt down bank 1.... Any advice on this behavior of pcm?????

Hi I like your way of explaining things but I'd like to see do a visual possibly a white board tutorial I bought my first scanner tool and would love to get the most out of it I wish I could of learned machanics 101 when I had the chance so in a newbie thanks
thanks for the video what if my LTFT changed from -22 to -5 in a second? long term went to 0.0% on both banks when I revved it. This is me reviewing the recorded datastream one of my af sensors isn't fluctuating at all, and i got code about the other one as well.
Thanks for the info....question however.....I have the same scanner and would love to know what the G and ? mean following the values. I can't find any info on what they mean. Any info would be awesome
drew bork G means graphing is available (click on ok/enter with the line highlighted and you have a graph... And the ? Is just info... Push it and read!
I want live data from from a closed loop system that is not showing me the stored information in the computer that is (+32.8 STFT) and (+32.0 LGFT). Code P0170 on a 2000 Jeep XJ with CEL. Code states engine is lean. Reality is engine is rich. Vehicle has been out of commission for some time, but now back on the road, running lean/rich. After clearing the code a few times, I went for another, longer drive (10 miles) and the scan tool was plugged in (Zurich ZR8), it showed the same code as Pending, but no CEL is present. Although I can smell a rich exhaust, it appears the engine is “adjusting” to run cleaner and I hope that driving it will continue the trend towards improvement in exhaust quality. (poor fuel economy likely). How can I be sure I have cleared DTCs from memory, and obtain only closed loop live data going down the road? Do you driving 10 miles,, turn off the engine, plug in the scanner, turn the engine back on and immediately clear codes, then quickly drive another 10 miles to get the correct, real-time, closed loop data?! Yeah, that’s a mouthful, but I think you will understand my question. Thx to you and anyone else that can give me the step by step for clearing the codes and getting solid numbers from the closed loop to figure out what is going on. ( I can’t find a vacuum leak using the spray-mist test). Thx
Ok questions on something have a 2003 grandam getting crap for gas mileage change plugs wires filter was told do a live Scan I did my longft1 goes negative to about around 5 to about 10 to 13 when I press on gas was told if your on gas it should be + not - but your video says + or - ok told could be a cat going bad but not codes just poor gas mileage and car seems have power so are my fuel trims ok hope you can understand how a write it all trying figure what going on with my car thanks
Hi my o2 sensor O2B1S2 shows "0" voltage whilst O2B1S1 fluctuate 0.5-0.7+ volts is that mean that o2 sensor that has 0voltage is down and needs to be replaced. Long fuel trim 25+. Thank you great video
Take off the sensor and get a volt meter. Set it on Ohms. Look for the two cables that are the same color. Connect the voltmeter to those two ends. You should see a resistance between the two.
hey i found your video very helping but i have a question my o2 sensor 1 is rapid and my 02 sensor 2 is steady and im getting a p0420 now in your video you say the opposite do you have a explanation for this?
The live data on my scan tool indicates that the voltage for my upstream 02 sensors fluctuate just as they are supposed to. However, my downstream O2 sensor remains flat at 0.000, so what does that mean? What kind of voltage should we see? For your downstream O2 sensor, it remained around 0.030 and 0.040. So, what does that mean?
Highly chance im wrong im still new to learning about cars but from what ive seen is that downstream pretty much checks up on your cat to see if its working... dont take that advice highly though

how can I use live data to help diagnose a slow response camshaft code
I have same scanner how do I change the Celsius to farernheit on tempeture
Is there a way to read fuel injector pulse width on this scanner? I have Autel AL319
My TP at idle is sitting at 17.6% and is electronically controlled does this mean this needs to get replaced?
so, the engine needs to be running in order to read the live data via an OBD2 scanner?
Will or should the TPS read 0.0 at idle. Or will different cars read different v at idle.

Hi have a question.
Honda pilot 2003 3.5 just two sensors up and down.
Bank 1 Rich. STFT S1 -27.3% STFT B1. S2. -27.3% steady on both.
Oxigen Sensors output V ( B1 -S1 0.855 V
(B1 -S2 0.035V
How come if S1 is reporting a Rich
Sensor 2 is reporting Lean.????
My problem is that pcm is taking fuel away
From bank 1 to the point in which
That bank is not working...
If you disconnect those 3 coils from bank 1
They don't miss.
But I you reconnect the bank and
Do the same thing to #2 bank each cylinders
Started missing if you disconnect all 3
Engine won't die.
Pcm supplies supplies fuel to bank 1
And then they are running...
This is weird !!!
Then if you reconnect bank 2
Pcm shutt down bank 1....
Any advice on this behavior of pcm?????

So does this tell if the cam phaser is stuck open or closed ?
What should maf sensor show on live data? Thank tou
Thanks for the info....question however.....I have the same scanner and would love to know what the G and ? mean following the values. I can't find any info on what they mean. Any info would be awesome
drew bork G means graphing is available (click on ok/enter with the line highlighted and you have a graph... And the ? Is just info... Push it and read!
Is there a way, using live data, to see if a cylinder misfires?
My O2B1S1 volts shows its 3.550. And my car is running rich it burns alot of gas. What can I do ?????
To the point.. excellent.. Thank you!
Can you please do the All the scanning and graphic chart
, explain how that work 101, if you can ,thank
My TP (%) 9s at 10.6 at idle. But yours is at 0.0 unless you hit the gas. Is that telling me something?
yes your tps is bad
I want live data from from a closed loop system that is not showing me the stored information in the computer that is (+32.8 STFT) and (+32.0 LGFT). Code P0170 on a 2000 Jeep XJ with CEL. Code states engine is lean. Reality is engine is rich. Vehicle has been out of commission for some time, but now back on the road, running lean/rich. After clearing the code a few times, I went for another, longer drive (10 miles) and the scan tool was plugged in (Zurich ZR8), it showed the same code as Pending, but no CEL is present. Although I can smell a rich exhaust, it appears the engine is “adjusting” to run cleaner and I hope that driving it will continue the trend towards improvement in exhaust quality. (poor fuel economy likely). How can I be sure I have cleared DTCs from memory, and obtain only closed loop live data going down the road? Do you driving 10 miles,, turn off the engine, plug in the scanner, turn the engine back on and immediately clear codes, then quickly drive another 10 miles to get the correct, real-time, closed loop data?! Yeah, that’s a mouthful, but I think you will understand my question. Thx to you and anyone else that can give me the step by step for clearing the codes and getting solid numbers from the closed loop to figure out what is going on. ( I can’t find a vacuum leak using the spray-mist test). Thx
Just what I needed to hear
So while this data is being recorded is the car parked? Driving consistently at what mph?
ASKED to soon lol
Just curious what brand of scanner you’re using.
What if short term fuel trim is at a constant negative number?
This is mine when I give it gas. What can it be? 02 sensor 1 stuck rich
im@trishperkins5416 I am not following you. is this question or answer to mycomment?
Ok questions on something have a 2003 grandam getting crap for gas mileage change plugs wires filter was told do a live Scan I did my longft1 goes negative to about around 5 to about 10 to 13 when I press on gas was told if your on gas it should be + not - but your video says + or - ok told could be a cat going bad but not codes just poor gas mileage and car seems have power so are my fuel trims ok hope you can understand how a write it all trying figure what going on with my car thanks
How do u live stream data, I can’t see this option, I did it once and now it doesn’t pop up, maybe I have to run it a while idk I just bough it
Hi can you real the reall kilometers of the car with this scanner
Will the zr8 read oil pressure in Live Data
Hi my o2 sensor O2B1S2 shows "0" voltage whilst O2B1S1 fluctuate 0.5-0.7+ volts is that mean that o2 sensor that has 0voltage is down and needs to be replaced. Long fuel trim 25+. Thank you great video
Take off the sensor and get a volt meter. Set it on Ohms. Look for the two cables that are the same color. Connect the voltmeter to those two ends. You should see a resistance between the two.
hey i found your video very helping but i have a question my o2 sensor 1 is rapid and my 02 sensor 2 is steady and im getting a p0420 now in your video you say the opposite do you have a explanation for this?
Thats ur cat
@@good2boost529 MEOW
The live data on my scan tool indicates that the voltage for my upstream 02 sensors fluctuate just as they are supposed to. However, my downstream O2 sensor remains flat at 0.000, so what does that mean? What kind of voltage should we see? For your downstream O2 sensor, it remained around 0.030 and 0.040. So, what does that mean?
Highly chance im wrong im still new to learning about cars but from what ive seen is that downstream pretty much checks up on your cat to see if its working... dont take that advice highly though
