Well I took of the y-pipe and I have both old 02 sensors hanging and I followed the wire for the front bank 02 sensor and unclipped the clip. I tried to follow the rear bank wire, but I can't seem to find where it goes. If someone could help me, maybe even with a picture I would really appreciate it!!!

 

It goes way up (wedged in between the PS lines) and the plug is up on the intake manifold.

 

that doesn't sound fun

 

Yeah I got it and installed the new one, thanks man!!!

 

I still can't seem to find it. I'm probably just not looking in the right place. Its supposedly behind the cat, but I'm apparently blind.

Help please?

 

4 year old thread, not even related to your problem if you're talking about the downstream sensor.

Are you looking for the post converter or the right bank O2 sensor?

Apparently you're not even in the right subforum, either.

 

I did a search, and this is what came up. Yes, I'm looking for the rear downstream sensor. I saw another thread where someone had replaced the cat with a straight pipe and reinstalled the sensor, but that didn't help me either. If you can direct me someplace else, please do.

 

Well, the 5th gen forum, to start.

This is the 4th gen forum. Most of the A32s only have 3 O2 sensors, you have 4. That's why you're having trouble locating an O2 sensor past the main converter, because you don't even have one.

Rear downstream is in the bottom of the Y. The harness connector will either be white or gray, third from the right as you're standing in front of the car, looking at the engine bay.

Also, no need to even search, it's in the stickies in the 5th gen forum. It even says 'O2 sensor locations' in the title of the thread...

If you have a question, first check the stickies...

 

Thank you. I found it. I do appreciate the link, too.

 

Pmohr strikes again!! Another problem solved and with NO handy side kick to boot!
