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.
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!
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 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...
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.
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!
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!
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.
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
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!
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.
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!!
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!!!!
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
Scotty said the Oxygen Sensors are hard to replace; however, easy to plug in; however, it was easy to replace my sensor, but it would not plug in and "snap" in place. It's tight so my hand barely fits and when I push the connections together there was no SNAPPLING in place. I'm not sure if it was totally connected, but it was working okay. Others, too, have had issues with the connections "snapping" into place even when they are OEM replacement parts.
@@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

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.
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.
Just came across this and I'm impressed! I have a 2007 Toyota Prius. Check Engine light is on. Brought the car in to a mechanic and was told it's the heater for the "passenger side" oxygen sensor. Was also told it would cost $700 to replace (parts and labor). I'm a woman, and after seeing your video... Methinks someone's fleecing me. I have done my own car work in the past (LONG time ago - starter, brakes, misc on a 1980 Datsun 210!). Am I capable of replacing my own oxygen sensor in a newer Toyota Prius?!
I pretty much do all my own work on my truck; brakes, oil changes, steering rebuild, suspension rebuild, drive belts, distributor, plugs, wires , and fuel filter. Buy and download the factory service manual for your car. Watch a lot of videos and visit car forums specific to your vehicle. If you're pretty handy and motivated, you can fix most things yourself. I also have a problem with handing money over to people who think they can take advantage of you. Given the look of my truck though, I've never personally had anyone try to take me for a ride. I just hate parting with my money in labor costs. Good luck. Just be aware, most things rarely go as smoothly as the book or video shows. At least with my truck anyways
after replacing the downstream sensor, i couldn't believe how much of an effect it had on driving, especially from a stop. much, much smoother, and low amounts of gas didn't cause the engine to judder. just wow.
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.
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
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.

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.
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.
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
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
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
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 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-5icTmYItwiE.html
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.
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?
try the sensor and pray, cause many things can trip that code, from vacuum leaks to weak fuel injectors. You might try my video "finding engine vacuum leaks with a cigar" also.
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!
Often a weak fuel pump, try pressure testing it first. If not, try my video "how to clean fuel injectors on your car": AND find if you have a vacuum leak on the engine using my video "finding engine vacuum leaks with a cigar"

Will be changing bank 2 sensor 2 on my 07 camry v6. Of course, it just has to be under the car with the plug inaccessible unless you remove the bottom plastic plate. Should be at most a 10 minute job but this just adds to it. Labor at the auto repair is around $140- no thanks, will do it myself.

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
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!
Hello Scotty, do you have a video about P2096? when Post Catalytic Converter is too lean. I used FIXD scanner but it shows a list of possible reasons as: 1.- Heated Oxygen sensor (HO2S) Bank 1 Sensor 1. 2.- Rear Oxygen Sensor (O2) Sensor. 3.- ECM Programming. 4.- Oxygen (O2) Sensor. 5.- Heated Oxygen Sensor (HO2S) Bank 2 Sensor 2. But it doesnt shows a specific root.
I got my valve gaskets (front and rear) changed by Firestone..cost me about $500. After few days of driving the check engine light was on and this time it showed couple of codes, P1130,P1135, P1133. - Coolant Temp sensor- Coolant fluid is out, Air Fuel Sensor 1 Bank 1 harness issue. Firestone wanted to charge $200 for analysis, part would cost about $291+tax from Toyota dealer and another $200 for labor. Got Denso part 234-9007 an upstream rear sensor 1 Bank 1 (6 cylinder engine) for $96(from Amazon). A 22mm long wrench for $12, a PB Blaster and replaced it. While I was there bought a Engine degreaser and cleaned up the engine bay...the car sounds better and cleaner. After replacement, initially the engine smoked crazy...may be burning the extra degrease and settling in by burning the copper antiseize... drove about 10 miles and no engine check light yet.....thank you Scotty
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.
I've had three cars now that never threw an O2 sensor code.Now I know that one of the ways an O2 sensor goes bad is that it will still produce a voltage but it's too low.If your MPG's start going down but there's no O2 sensor code I suggest you test the O2 sensors anyway.On my current car, a 1990 Toyota Camry 2.5L V6, I never got an O2 sensor code but the car was running pig rich.I hooked up a voltmeter to the rear O2 sensor and VOILA,voltage told comp that it was lean when it was really rich.
