I have an '04 sc430 and yours is the first video, and I watched many, that actually gave me a good idea of where these things are located. Thank you!! Also, thanks for the reminder to take my time and not to get frustrated.
Are you saying the 2 front sensors (toward front of the engine) before cat are the same 02 sensor part #? I bought 2 was able to get the one in front right of the Heat Shroud, however the other upstream lower left... (the one going right into the pipe) that connector did not fit? so I had to return one.. I removed it and the holes on the tip of the sensor were different than the one on the right of the heat shroud.... Any info will help.. thx
The air/fuel sensors (before the catalytic converters) are the same. However, the engine is placed in the vehicle sideways. That means there are air/fuel sensors on each side of the engine. One is in the front (first one I described in the video) and the other is in the back of the engine, right next to the firewall (fourth one I described in the video). Hope that helps.
Hi ? I am harry , i live in France and i have à Nice car ; à lexus ls 400 96, but i have à problem ! Car make many smoge ( so fuel ) à the back i have change many parts in the engine and the 2 oxygene sensor before catalytique ! Same problem ! Could you think it is 2 sensor after catalytique make many smoge ? Thank you , harry
Hello! I have a 2013 Lexus es350 with 108k miles, I’m the second owner and I got a check engine light. I went to autozone and the codes were P0441 P0455. The worker who has really helpful told me that it was probably an 02 sensor. Any thoughts as to what it could be? Im going to the mechanic shop two days from now. Thanks!!
I changed all 4 on my 08 GS350 with 123k 2 upstream and 2 downstream the way I change them because I was getting puff white smoke on warm startup and the mechanic told me your o2 sensor might causing this but he was wrong , good luck 👍🏼
I've got a lexus rx330 2005 and my check engine light and traction off light came on so I unhooked battery cables and hooked them back on lights went out but was running rough checked and it was out of coolant put coolant in and back to normal next day I cranked it maintenance required light was on and running rough turned it off and barely cranked sat one hour tow truck guy cranked it drove it on truck said seems like it is ok but I went ahead and sent it to garage any idea what could be wrong with the crazy thing
Thank you for watching! The part numbers may be the same or similar, but since you have a hybrid, I strongly recommend you check RockAuto.com for the correct part numbers.
@@gdupler1966 I seen that you used ramps and I'm going to do the same I just didn't know if I'd be able to reach it. I have a an extension and O2 sensor socket like you have. Thanks for replying.
Just my opinion, more emission issue than drivability, but I don't like having the codes. If it were me, I would try a cat cleaner in the gas tank first. If that doesn't work, replace the sensor. If that doesn't work try: th-cam.com/video/t4MCUwaeqA4/w-d-xo.html
I heard there’s something called “ adaptation values “ which you should do it with your OBD after replacing any oxygen sensor so they can read the new date but not the stored old data. Any idea on this one ? Great video by the way 👍🏼
Thanks for watching! I have heard of the term with certain codes like P2097. Whenever I have replaced sensors on Toyotas I let the PCM figure it out and see if it resets. If not after some short drives, I reset it with my scanner.
@@gdupler1966 in my case acutely I never had any codes or any engine light but my car was puffing white smoke at startup and the mechanic says your down stream O2 sensors are bad and that’s what cause that smoke !

@@costantineyoussif6679 those two codes point to the upstream pre-cat air fuel sensor on the left side not the downstream.

@@gdupler1966 thanks for responding, mine gave a P0420 code and it idles correctly. I’m guessing it’s the catalytic converter but it might also be the O2 sensor. (Catalytic system below threshold. Bank 1) what do you think?

G, About how long would you say this took you? 1 hour? 2? Mechanic wants to charge $750 for this job (parts+labor) and I'm thinking the parts are under $200 and no way hes gonna spend 4 hours on it LOL
Maia, good question. I would think an experienced mechanic would take 2 hours tops. I purchased the Denso OEM sensors from Amazon for right around $200. I understand that mechanics have to make it worth their while, but if it were me, I would check some other estimates.

wondering if you saw any improvements with mpg? I have no codes but getting about 19 mpg freeway. vehicle has been religiouly maintenanced.
Yes, a little, probably about 1 mpg. Changing plugs helps too.
after using the o2 socket where does the other side come unplugged from? i got a 04 rx330 and don’t want to just pull it out without undoing it
I would recommend unplugging the wiring harness before you use the socket. Otherwise, it will twist the wiring and make it more complicated.

The combination of those codes usually means you need a new gas cap. I would look at that, check the vacuum lines, and probably a PCV valve.

P0133. It only indicated one sensor, but due to the age and mileage of the vehicle, I replaced all four sensors.
