Your whole approach and methods are about as top notch as anyone could expect from an instructional video. The details you point out make all the difference between you and most other RUclipsrs. Lucky for me I have the same exact engine setup in my '02 LeSabre. You've been a great help to me, and I greatly appreciate all the effort you put into your videos. Be well.
Great information. I have the same problem with my exhaust 02 sensor. I thought that it was my catalysts converter 02 sensor. My engine light came on and read 02 sensor bank 1. I have some basic knowledge about car parts, and repairs. However though, I wasn't knowledgeable on this 02 sensor bank 1. Instead of first asking Auto Zone to let me actually see it. I went ahead and purchased the wrong 02 sensor. I got the one for the catalysts converter (under the car). I paid $ 20 for the part, and $ 65 to have it replaced. Only to realize that my check engine light was still on. After doing some though research I finally realized, and understood what was the correct part. I had purchased the correct. I was scheduled to have an auto repair shop to replace it for $ 45-65. However though, after seeing your video, I believe that I can replace it myself. Just today I did exactly what you said. I removed my engine cover. I looked directly behind the engine. Their it was located. I placed my hand directly on it. Yes it really looks so easy to replace. As you illustrated. All I need to purchase six inch extension, and a sensor remover tool. I already have a ratchet. The only this I am concerned about in making sure I properly unplug the connection from the old 02 sensor. I have a 1999 Buick Park Avenue ultra supercharged engine 3.8. This is the original 02 sensor. Again thanks for your video I hope that I do it right 😊😊
Thank you but watching this video it taught me what not to do that I was going to do in the first place and I thank you very kindly for the advice and the equipment have a great day
Could this be the reason I'm getting a P0420 code? My upstream sensor wire melted against the exhaust manifold . I repaired the wire but the code came back.
Thanks for the informative simple video. I'm having trouble rotating the sensor with my weak arms. I'm using a ratchet so maybe it's the tool. Will try tomorrow
Hi Keith! 2 questions...#1) What connector is connected to the 02 sensor connector? Is it the EGR connector? And #2) I just replaced my 02 sensor on my 98 Park Ave (thanks to your vid), and, for some odd reason, I now have 2 female connectors that I am supposed to connect back together??? How is it even possible to have 2 females? So...the 02 sensor connector is female & the EGR? Or whatever the connector that is that's supposed to connect to it is identical to the 02 connector! I'm so confused. :/ Help please. TYSM in advance! (I wish I could send you a pic of what I have here but there's no attach thingie).
I tried to do this on my 2001 chevy monte carlo ss 3.8 engine it was merely impossible because the transmission stick pole is in.the way how long is your socket wrench
For removing the plastic cover, some of those cars with the Supercharger have a bolt that screws into the top, in the supercharger that'll need to be removed as well
So, you changed out two O2 sensors that were working and you had codes that said that they are working? And are you worried that your new O2 sensors won't work? Why are you worried about them continuing to work? I'm not sure I understand your question.
p1183 isn’t an o2 sensor code 😭 P1183 is low power in your fuel pressure regulator. PO140 or PO135 is your O2 sensor i don’t remember which is which but the other is mass air flow sensor i just get them mixed up sometimes:
Hello, I have a question, the pontiac grand prix gt 3800 also has 2 oxygen sensors and they are the same as in the video? Thanks and greetings from Mexico City
@@BarboursAutoHelp i need to remove the oxy sensor it is right in front the spark plug I am trying to replace I tried the 7/8 ths wrench from auto zone but it could not turn in the space. ( No I'm not using a sensor wrench to replace my spark plug) thank for your help. Stephan
Oh ok. Just making sure. Of course you can find them on Amazon. Just search for oxygen sensor socket. They also have them at most parts stores. Sorry I dont have tool numbers. But, you shouldn't need numbers. Are you changing spark plugs on a 3.8L. If so I have a video that should help. On the 3.8L in the video sensor removal isn't needed to replace spark plugs.
If my car hesitates when I started up and then after a while it drives normal but then when I shut it off and started up and it hesitates again would this be because of the 02 sensor?
Really good video. I paid an auto shop to replace mine because I didn't have the time and I hadn't researched my check engine code. Makes me wonder why I was charged $342 to replace it after I explained that my code reader said P0135 O2 Sensor Heater Circuit Bank 1 Sensor 1.
Well, just because your code reader gave you a code for the heater circuit it doesn't automatically mean that the O2 sensor is bad. There is more to the circuit than just the sensor. There is a fuse, O2 sensor, wiring and the PCM that all make up the circuit. A failure in any one point along that circuit can cause this code. So, they probably ran a pin point test on it to insure that they were replacing the right part and then of course you have the cost of the part and the labor to put it in. So, $342 may not be a bad price for having a pro diagnose it and replace the part for you.
If yall ever come across that the car want crank sometimes. I replaced crank and cam sensor. And wire harness. $100. FOR ALL parts on ebay. Car run fine.
Thanks a lot man to bad I didn't see this video until after I paid the shop to do it (about 2 days ago). I recently watched your spark plug tune up and did that for my Bonneville it was a big help. The diagnostic was a code for 02 sensor but even changing that didn't fix the problem so now we are looking at a new fuel filter. Other then this issue the car has been so good to me. Thanks for the videos. Do you have one on a passenger window that won't go down?
Changing an O2 sensor on a 3800 is so much easier then say a 3500 that's in a Chevy uplander. It's just the type of vehicle rather than engine, but nearly everything is a little tougher. With so much room up front you would have thought the engineers would have thought that thing out a little better. The cars with the 3800 on the other hand, a breeze compared. Just look at the spark plugs.. easy. Alternator.. easy. Coils.. easy and up-front. The crazy thing is the 3800 has roughtly the same power output and the 3800 was used in earlier vans on the same platform.
I have a 2003 dodge caravan 3.3lv6 with the code reading p0135 my 02 sensor its on the right side behind the engine i try to unconnected the connector its not coming out and i have a p01684 its my battery terminals needs to be changed
take your wipers off first( make sure you remember to where the wiper rest when you out them bac on) n then the housing..doesnt take long n is a easy job if you want to get to the sensor. makes things alot easier..for me anyway.
my sensor came with the wire and harness. So to remove the sensor, I just cut the wires and used a deep dish socket on it. Installation, well, not as fun. But it is not too hard to get a wrench on the sensor. This is for those of you that don't have that special slotted socket he used. The sensor can be tough to get out so I personally recommend you use a whole socket on it. The new sensor will go in much easier
The socket is only $10-15. I would not cut the wires on the new sensor. Just spend the money and get the socket. It may save you from ruining an expensive sensor.
Thank for the video. But I just bought a camaro with that motor and I need a catalytic converter. The shop I went to told me to get a catalytic converter with 3, O2 sensors. Is this correct ? Thanks
Hey, I just bought this 99 Camaro with no exhust or catalytic converter. It has the 3800, V-6. And a shop I went to. The guy I know that works there was't there. And his wife that works up front told me that if I bought a cat. online to make sure it came with 3 sensor. Is that because, I will need to replace 3. Or the cat itself has 3 ?
Some shops like to replace the O2 sensors with the cat. The converter shouldn't come with sensors... at least the ones I get don't. You may have to ask for all the sensors when you get the cat.
Thak you very much for your response. I have figured out that two of the O2 sensor are on both side of or behind the headers and the third behind the cat. On this year Camaro.
Better idea - use a 1/2"-drive socket over the top of the sensor socket, and use extension(s) and a 1/2"-drive breaker bar. And never use a pipe over a ratchet wrench handle for additional torque leverage because you'll risk damaging the ratchet.
@@BarboursAutoHelp No, that was my own extra friendly advice, because I happened to ruin a Craftsman 3/8"-drive ratchet wrench last weekend by using a pipe over its handle to leverage the O2 socket. After that mistake I realized AFTER my mistake that the O2 socket has a hex that can accommodate a socket over its end, and a 1/2"-drive is much stronger for torque and the use of a breaker bar basically eliminates the need for a pipe. I learned that a ratchet wrench's internal mechanism can't really withstand the stress of a pipe used with it, and that's what a breaker bar is for. (I also needed to use a universal adapter to solve the angle problem reaching down to the O2 sensor.) I also learned that the type of O2 sensor socket with the extra-wide slot that eliminates 2 of the hex corners (the type that Harbor Freight sells) also doesn't work because it slips and can strip the sensor's hex head. I went to Pep Boys and bought their socket that has the narrow slot and all 6 hex corners, and it worked (after soaking the joint with Liquid Wrench). That sensor can be a beast to break free after years of being subjected to exhaust heat. The point of my post is that my mistake (and loss) and friendly advice can result in another's gain. "A wise man learns from his mistakes, but a still wiser man learns from others' mistakes." Thanks for the video and thumbs up.
@@motrhead69 Why not? That's the best alternative yet. If the 02 sensor is intended to be replaced, what's the point of saving the wire? In my case I removed the sensor in order to test it, with a small chance that I may keep it. But I like your suggestion. Thanks.
You are 100% correct concerning vehicles that are equipped with bank 1 and 2 sensors. And thank you for pointing that out. However, the vehicle featured in the video only has one up stream and one down stream O2 sensor. Thus they are both classified as Bank 1. Up stream is bank 1 sensor 1 and down stream is bank 1 sensor 2.

Does a 84 Buick regal have an oxygen sensor
Probably but not for sure. Pop the hood and take a look.
Is this the upstream or down stream O2 sensor
up stream
Would this sensor deteriorated cause p0411 issue?

If my car hesitates when I started up and then after a while it drives normal but then when I shut it off and started up and it hesitates again would this be because of the 02 sensor?
Probably not. I'd have a hands on tech take a look at it.
What size is the socket? 22mm or something else...
7/8"
What size is shock and can you put an open wrench on it and what size
7/8". I would not suggest using an open end wrench. This could potentially round off the nut of the O2 sensor.
So what is the torque value to tighten it down to?
Don't have it. You will need a repair manual for that info.
Very helpful. No longer need a mechanic
Glad it helped
thank you I have a 98 Malibu and some of tip are super helpful.
Socket millimeter size? Please
7/8" not metric

Not usually. On older vehicles it can really make the engine run poorly though.
