Scotty Kilmer , I got a pretty bothersome problem, a couple months ago my car threw a check engine light for both upflow o2 sensors. I went to a mechanic that I've known for 20 years that hasn't ever steered me wrong and he replaced both of them. How ever every once and a while the check engine light comes back on and it reads those 2 upflow o2 sensors. After a short while the light will go back off though.
The constant symptoms no matter if the code is there or not are:
*The car idles at around 500rpm
*At stop car will shake and rpms will drop to almost stall and bounce around before going back to 500rpm
*Very poor gas mileage
*I believe slower acceleration by a little
I'm also pretty sure i have an exhaust leak by the sound of it.
Scotty Kilmer how to diagnose engine knock which spark plugs and bad wires
Scotty Kilmer hey i scan it and it shows me the code but dosent tell me which bank is it, what do you recommend i do!
i dont mean to be so off topic but does anyone know of a trick to get back into an Instagram account..?
I stupidly lost the login password. I would love any tips you can give me!
@Kaysen Griffin Instablaster =)
I had my check engine light come on.. I had a bad O2 sensor. thanks to this video I was able to replace it in the parking lot of pep boys for about $75 bucks.. including the socket. Pep boys quoted me a $370 for the part and labor for the "2 hour 45 minute job" Took me all of 45 minutes from the time I walked in to pep boys to the time I drove out of the parking lot
+A.J Blatnick That's the exact reason why I love to work on my car myself.
+A.J Blatnick That is beautiful saved like $300 (= a lot of hourly work hours)...Everyone should learn how to fix their own cars these days b/c repair costs go up all the times. Anything car problem costs $300+..crazy...
+wesandkirsten it was pretty busy... and the guy had no clue on what sensor I needed
This cracks me up man!!!
Mechanics & Mechanics lots just want your Money...all they are is... Money Pit, & thief!!!
SMH!!
A.J Blatnick wish I was smart enough to just fix my car lol
You're a life saver. My car died on the highway this morning and then again at a red light once I exited. Made it to an auto parts store and did the repair in the parking lot thanks to your tutorial. Just wanted to say thank you. You're the first place I turn to for how to's.
This man deserves a medal.
My car has been in the shop for an entire week and still haven’t no call from the mechanic I literally told him it was an oxygen sensor and dude is taking his sweet time fixing it I’m considering just tellin him never mind and doing it myself
Scotty you are a LIFE SAVER! I've had several problems with my PT Cruiser GT lately. My car was throwing codes like crazy! So I cleaned the ecm with the electrical spray you recommended to remove the oxidation and so far so good, you saved me big bucks! The only code left is bank 2 o2 sensor downstream so after watching your nifty video and as soon as the storm passes I'll be out to change that sensor. Thanks a million! True fan of your work!
Thank you yet again Scotty!! I have used after market parts since I have been working on cars and I am 60 years old. I cannot remember replacing a part with an exact OEM part. It never made a difference. But I never changed an O2 sensor. Well after replacing my sensor with an after market part, that the seller said is compatible with my car, failed as soon as I started the car, I looked to see what "Scotty" had to say. I should have done that first. I replaced the part with the OEM sensor and now it works! Thanks again!! You rock Scotty.
im so happy i found your videos! i just changed my spark plugs today in a 95 saturn sc-2, found oil in them, so watched your video on how to change my gaskets, and since oxygen sensor was next on my list, i was thrilled you had this one! bought my car used, in rough shape, and im slowly nursing it back to health with your help!

they are complex feedback systems, and as such, can do many different things when they go wrong. And testing them requires all kinds of experience and a freeze frame oscilliscope to even start testing them out fully. They can cause a rough idle, but so can tons of other things. Most people pay a mechanic to analyze them with a dealer level scan computer and watch the wave forms they put out while doing certain tests of the fuel system.
worn timing chains often do that, check that out first. Also check for vacuum leaks on the intake, they are known for that too
So glad you had a video on this. My crappy 02 pt. cruiser has been suffering from this particular situation for about a month and now I know what I need to do. Thanks!!!!
Thanks again.
I did the catalyzer cleaning (it looked pretty good before the cleaning with no melting points) and it was a pretty PITA. Until now not even one single code appeared, I hope that the cleaning help me get rid of the problem.
Thanks a lot Scotty. Keep up the good work!
I always enjoy watching your videos. You keep it interesting like no other. Thank you for all you do.
Joe Governale agreed
Thanks Scotty for a very precise, quick and to the point video.
Scotty is the man!!
I only use factory oem sensors as they are very critical for the cars running and I see aftermarket cheapies often not work correctly.

Thanks for the video! I'm gonna be changing my sensors and this is exactly what I need. Thanks man!
Thank you for posting this. I have a Hyundai Accent and the 02 sensor went out. Used your video to change it out and had no problems.
if you're talking about the power voltage supplied to the sensors, either the computer is bad or the wiring going to the sensors are bad lowering voltage. fuel pressure varies for all makes and models, any auto parts store can tell you on their computer
Love your channel. Lots of information. I have a Saturn Vue 2007 V6 with Honda engine at 120k miles. It started to idle a little rough (not terrible, but definitely not smooth) weeks ago with very occasional misfires of all cylinders. No other error codes. New timing belt and water pump. Changed MAP, air temperature sensors, PCV value, purge valve and EGR. Air intake manifold cleaned. Throttle body cleaned (not dirty at all). Fuel injector cleaning additive used twice. Always used neighborhood gas station gas which is certified TOP TIER with STP additive for fuel injector cleaning. They all had no effect on rough idle. OBDII scans consistently show a few (negative) percentages like -1% to -5% fluctuation, rich for STFT Bank 1. Bank 2 STFT is always lean. +3% to 14% fluctuation. Why Bank 1 always rich and Bank 2 always lean? Didn't see vacuum leak when I did a smoke test. Lazy or faulty O2 sensors? Unlike other cars, this car's OBD data does not give upstream O2 sensor voltage output (broadband sensor I guess). So I cannot check 0.1 - 0.8 V O2 sensor oscillation. Its downstream sensors' voltage responses can be plotted by OBDII scanner. They oscillate actively between 0.1 - 0.8 V as expected. I need some help here. Thanks.
it's anti seize and electrically conductive at the same time
Scotty, your videos are amazing! I replaced the upstream O2 sensor in my 2003 Mitsubishi Galant with the factory brand (Denso). I also cleaned out my throttle body and the mass air flow sensor (with mass air flow cleaner). After doing these three things, my car idles so low that it dies. I tried unplugging the battery overnight, hoping that it would reset the computer, but it still idles too low to stay running. I have to keep my foot on the gas to keep it from dying. Any ideas on how to fix this problem? The idle was fine before I did these three things.
Hey Scotty big fan!! I actually have a 2004 sequoia with the same problem, I followed your video step by step and managed to change the sensor myself with just $51 bucks!!
Scotty rocking the Cobra! Fun and informative. Thanks for the great videos, Scotty.
Love the Videos Scotty !!!

I think it would be cool if you made a video on how to test upstream and downstream sensors using a live data scanner. I know it depends on the type of sensor for how to test them, but it would be very useful information and you won't even have to get your hands dirty.
Scotty, your videos are the best! You have saved me some serious grief at times. Also ive learned a lot and saved cash also. thanks Tom.
Thank you Scotty! I just found out my car transmission gasket was bad and had leaked all the fluid! Will fix the exhaust pipe issue soon! ;) keep up the good work and thanks for all the wonderful videos! Cheers!
hondas carbon up inside the engines, try my video "how to clean fuel injectors on your car'
Scotty Kilmer hey Scotty, is a 2003 Toyota RAV4 with 128k miles w/ a 02 sensor problem worth $3200
sure can, I was actually surprised by the handling ability, especially at higher speeds.
Why did it only take you 2 seconds to replace these and Google even a shop said it will take 4 hours
@@lasvegascream1799 anytime you take your car into the shop just always have the preconception they will do their best job trying to discretly make money off of you. If you're bewildered, you should see how much some places charge for an oil change x_x
I just replaced my O2 sensor after a P0051 code on the 2003 4Runner V8. I appreciate your video!
Thanks to this video, my new 1996 Ford Explorer was fixed before it even had a real problem. Yeah, I bought an old SUV, but the older they are, the easier they are to fix, and it's just new enough to comply with OBD2 scans. Also thank you Scotty Kilmer for giving us the tip about BlueDriver.
SOO much headache and expense averted.
hey Scotty, I was just wondering if this is the same way to fix the oxygen sensor on a 2002 Mitsubishi Montero? Great video by the way!
yeah it’s the same way lol
I live in texas, but ford sends me new cars from detroit to road test.
How do i loosen a sensor that wont budge after applying wd40, 7/8 socket and cheater bar? Have been trying all day to change the upstream sensor on a 2011 chevy equinox 2.4l but this thing is welded on here, its at a weird 45 degree angle and the heat shield being in the way makes it complicated as well.
Thanks Scotty!!!, Just changed mine today, just with this video. Thanks!!!
Sure will scotty just to let you know i watch you every saturday morning even when i work weekends i still tune in to you (the best mechanic i have ever see) :) thanks scotty.
Ok, I subbed when you popped outta the trunk 😊😂 ty!
I LOVE THE WAY SCOTTY GOES"UUUHHN"WHEN HE PULLS ON SOMETHING REALLY HARD!IMMA TRY THAT WHEN I HIT SOME COOCHIE FROM THE BACK!"UUUHHN"
LMFAO wtf
💀💀💀😂😂
Jason Waters 🤣🤣🤣
Jason Waters that’s assuming you actually GET coochie...... which by your comment I kinda doubt.
Great Video Scott!! Keep up the good work. For the mechanically inclined, your videos are quite inspiring.
Man Scotty is that DUDE! I appreciate you man!
Scotty Kilmer - Is copper package the name of the thing you used in the video?
Maybe it's copper anti seize
Idk it looks same.
If yes then it's function is to prevent the thread from rust welded on the exhaust.
My 2010 honda civic is slightly hesitating when I take off in 1800-2000 rpm range. And has low idle at times... can that be a dirty throttle body?? I already cleaned the MAF sensor... no check engine lights.
SouthernCali909.PEN1.737 I don’t know if you fixed it or not but sounds like a idle air control sensor or a tps sensor which means throttle response sensor try both I had the same problem I just replaced both , hope it helps.
Signs of a bad O2 sensor on its way out.
Thank you very much Scotty for showing us how to change an O2 sensor. Regards.
Good video. Easy to follow & understand. Thanks, Scotty!
Who do you get the electrical clip off? I tried for hours to get mine off today and it wouldn't budge.
caseybv74 yea, some of those clips are like chinese jig saw puzzles. But they all have a release catch, look closely, most squeeze really hard in then pop off. OF they have a tang you pry out, then they unsnap
Those clips are why non mechanics are losing their poop with this stuff.
Sometimes, you just have to look at it for a while and use your brain.
Mine is stuck on, how do I get it off?
do we need to disconnect the battery before inatalling?
Not needed but just to be safe disconnect the negative terminal of the battery.
Not unless you want to reset the drive cycle monitors.
Merry Christmas Scotty!!! Thanks for all your videos wish I had a chance to meet you
Thanks for being an honest mechanic.
My 2005 kia Sedona lx has a bad oxygen sensor. I don't know where to find it or how to remove the engine cover thing. The van will not start at all and I have no tester so how do I know which to replace. Please help!!!
Kristen Mueller first, you need to know which sensor has a problem, so go to an auto zone, they scan em free. Then e mail the code here, it should show which sensor is bad
I wish my 99 Blazer was that easy to fix ! I changed the 02 sensor and the light still comes on after I had it cleared !
@@baldy194859 disconnect the battery 60 seconds and it should clear and it won’t pop up again
@@scottykilmer I got a code from auto zone but it didn’t say if my upstream or down stream sensor was damaged
Which is raises the question which is spark plug number 1???
take out the spark plug which you think is no.1
start the car
you should get a check engine light
hook up your scan tool and it should give you a code and message which reads: "Cylinder [spark plug number] misfire"
try this on all cylinders until you it tells you that cylinder no.1 is misfiring
# 1 would be the most forward cyl on a V8. If you examine it carefully, you should be able to tell.
How about since he has an internet connection, look it up? Sometimes is written right on the engine manifold.
He asked a good question and someone answered,... on the internet.
google it is your best bet, they all count them differently
Hi Scotty..cant thank you enough but am grateful of all what you do and share. I learnt alot from you Thank YOU.!!!
I watched your video how to replace sensor 1 bank 1 and I was able to do it on my own. Code P0130 popped up twice in the reading. Confident, replaced the Sensor 1 Bank 1 located before the CAT on my Mazda 3 2005 it was done accordingly. Reset the vechicle engine was off but then it came back in again after idling for 5 mins. After resetting it, unplugged the Negative from battery stepped on the brakes consecutively 5 times, idle it for 20 mins then turn A/C on for 15 mins then turned it off, engine light OFF, took it for a spin, turned it off turned it back in idle it 5 mins engine light ON. I had replaced the Upstream and Dowmstream with Bosch brand and new and old matched but engine ligjt ON after an 1hour. Ive cleaned the Mass Flow, the Throttle Body, reolace air filter, replaced the thermostat and the tempature control sensor and done oil change and new spark plugs as well. All that Engine light ON. Emmssion test also codes read NOT READY and failed. Ive also poured a gallon of Lacquer Thinner in a half tank drove it for half hour. All what was done to it made the car run smoother but still Engine Light ON code reading same code P0130 twice. What is going on. Need your help Scotty to solve my issue.
Another great informative video, Scotty! Thanks!
Can u use used O2 sensors
If you don't mind gambling.
I bet this guy still knows how to party
yes, oem parts are often much better, though they cost a lot more too they tend to last a lot longer than cheaper made aftermarket parts
this dudes just Awesome!!! simple and too the point with humor.
i was getting code p0420, someone told me it was the 02 sensors, so i replaced them both. now i'm getting codes p0130 / 0132 / 0134 / 0135, wth is goin on with my car?
Jim Van code 420¿ smoke weed!
did you use OEM sensors or aftermarket?
I learn a lot from your videos, Thanks Scotty!
Yup
Scotty's always great! The car fixit man!
thanks for replying my e mail scotty! I changed ox sensor on my subaru forexter xt as you said with OEM denso no engine light anymore all ok many thanks dear scotty you are the king of automotive ! salute from istanbul
I always trust your vids Scotty no matter how many videos I watch on you tube 👍
Great video, simple and well produced! TY!!!
I took your advice & changed both sensors it made a huge difference , the 2nd sensor (after CAT) definately needed replacing also to restore full performance. Luckily mine were only $20 each.
you are the man scotty. thanks for sharing and all you do
good ones come with a small package of the copper stuff used on them. If not, buy some from an auto parts store separately.
Yes, I never use bosch on any car that didn't come with them as stock sensors, as many german cars do.
I figured that's why I wanted to ask you to verify that fact. Thanks Scott your the best I love watching your videos very educational I learned some decent things about cars issues!
Thanks Scotty. Great Video.
This channel is gold. DIY
Scotty saves the day again with his video! I need to buy Scotty some coffee with the money he has saved me
Thanks Scotty, I always enjoy your fun demonstrations. I hope you have time to repond. I bought a 2004 fx35 last year and it failed smog check for P0138 and P0158 which are the post CAT o2 sensor issues. I went ahead and changed them both and I found out that it made no difference. When I delved into it a bit more I realized that all 4 o2 sensors once in operating temperature just show a steady voltage, the post CAT sensors go to 1.275 volts and max out, and B1 S1 is at .3 V and B2 S1 is at .64 with .01 v oscillation. When I accessed the ECM to see what is going on, I found that someone had simply joined the wires between S1 and S2 on B1 (and not B2). For the life of me I cannot figure it out why would anyone do that and why would ecm accept this. BTW, the car runs smoothly and aside from the "service engine soon" light on there are no issues. I also verified all 4 o2 sensors they are fine, even the original sensors that I replaced were fine.
Anyone out there has any idea what is going on. I hate to revert it back to what I think it is supposed to be and find out now that the car is not running smoothly anymore. I have to point out that mileage is not that great 14-17 mpg. I unplugged B1 S1 and drove it and it still worked but not smoothly, it got slow to respond to acceleration.
first, it must have the factory wiring, do that. then if it still acts up, odds are the cats got ruined. But you could try cleaning them as follows ua-cam.com/video/5icTmYItwiE/v-deo.html
Thanks Scott, I will be putting all 4 O2's in.complements on your vids. very nicely done!
instantly, i like this guy. subscribed!
yes
Hi Scotty. Good to see you there, saving people money by doing jobs yourself. I have four oxygen sensors in my '97 GMC with a Vortec V6 engine. I had the truck checked out at a shop just after I bought it and was told that all of the oxygen sensors were bad. I couldn't pay his shop rate of $250 to change all four. So I bought new ones (NTK Brand for a total of $220) and replaced two myself but couldn't get the other two out. I found a mechanic who came to my place and did the other two for $50. The truck runs fine now but the check engine light is on. Did I use the wrong brand of sensors or what?
it's running lean, and in those, almost always leaking intake manifold gaskets, one cow of a giant job. But, if it runs ok, you can ignore the light as the leaks can be rather small and not hurt anything. You need tons of tools and hours of time to replace those parts.
Men . You make things look so easy 👍🏽
Hi Scotty. Your videos are always a hit. I always lol when you do the tennis player grunt when doing something tough. Keep up the good work man ;)
Thanks Scotty Kilmer!
I used the UV Dye method to find where my oil was leaking on my Ford Escape and it was the timing chain cover, but that video showing me how to do that has led me to this video because the oil leaking down has completely soaked my 02 sensor and wire on Bank 2 Sensor 1...I think I may have found my issue when trying to accelerate....Thanks for the great advise as always Scotty! :)
What’s up Scotty really enjoy your videos very helpful
thanks for the info about the org. brand instead the aftermarket cheepy ones made a world of difference
Scotty: entertaining, informative, and nice intro!
You're the best SK !!!
Your Vids are So well done! thx BROTHER!!=
lol i love this guy's video style! subscribed!
sensors can go bad and do that, but so can tons of other things, like weak injectors causing sensors to show lean running. Try my video "how to clean fuel injectors on your car" first, that often stops that code on a toyota
This guy is a international treasure 👍
Thank you very much. Pretty useful information.
rarely, it's normally an engine problem doing that, like weak fuel injectors or head gasket leaks.
Aha this guy is great. I love the vids.
Very good narrative !!
Thanks.
Scotty popping out the trunk!!!! LMAO!! Gotta love this guy!!!!!
often head gaskets starting to blow. Try my tests "how to tell if your head gasket is blown"
Have been mentioning your site to other folks, very helpful.
replace the heated oxygen sensor on bank one, the one after the catalytic converter
Scotty Kilmer Thanks, always clear on your videos. I know u get millions of questions, and a will make one of them too.
1998 Ford Mustang V6. 3.8
Can a bad 02 sensor make it de-accelerate. Or something to do with the Gas, I thought was the fuel pump
Thx for the tips Val
