Hey everybody, I have been searching around the forum as much as I could have been without the search function... I know, I know, I will be donating soon. Anyways, I still haven't really found an answer to my question. 2 days ago my CEL came on, and I took it to AutoZone and I got code P0136 - oxygen sensor 2 in bank 1. From what I have been reading from other threads about this, the sensor is the 4 wires sensor near the CAT.

I'm still confused about which one I have to buy:

I'd really appreciate it if someone could help me out with this.

And... Is BOSCH pretty much the same quality as OEM for oxygen sensors? Or should I buy the one from NISSAN?

 

I have an original one from nissan for $90 shipped.

If you want the Bosch one it will be 13783.

 

The one you have is in original packaging and never been used?

 

that is correct.

 

I just replaced one for code p0135 (3 wire) with a bosch one from napa. I was skeptical about using the kind you have to splce it but it's been working great. It comes with everything you need to splice and instructions. Can't beat $65 either.

 

And it's the 4 wire one? I'm interested if yes.

 

What do you mean you were skeptical about the kind that I have...? I need the 4 wires one near the CAT. I believe it's downstream.

 

I meant for my car.

 

Well yea, but you replaced one of the others 2 sensors left (the 3 wires ones) with a 3 wire sensor, which is correct. Why would you expect problems? Because of the splicing you had done?

 

I just was not feeling great about something in direct contact with the ECU being spliced but I'm over those feelings now.

 

yes it is the 4-wire O2 sensor that is by the cat.

 

Dunno what the fuss is all about. Bosch basically created 02 sensors back in the late 80's i think it was, read that on some site

When i recently replaced my downstream 02 bad boy, it had both a nissan logo on it and a bosch stamp, so its ok just buy whichever one is cheaper

 

I have a used one with no codes when pulled off for $25 shipped (lower 48). The only reason I changed it is b/c I changed the front two and the car had 100,000 miles. Let me know if you want it and it's OEM.
thanks

Thanks a lot for the info dude. Highly appreciated. CEL went off afterwards? I read about people that changed it and CEL still didn't disappear.

 

Thanks a lot man, I'd rather buy something new though. I'm skeptical like that. Haha.

 

Sounds like a deal. PM me some pics?
