3.0 bank 2 downstream oxygen sensor location

[ayfour]

Cant find it.. I was told I can access it from the top of the engine, I found one but theres no way this is downstream, its almost directly after the headers. Im looking for the one after the cat.

Can anyone help? Where can this be accessed from? Underneath?

Thanks folks.

There is a picture in post 7 of this thread that shows the O2 sensors. The back ones will be fairly hard to get to from up top, but they are on the upper side of the cats. Good luck.

Thanks for that link. Looking at that pic, im thinking the one i saw was actually the post cat sensor. Seemed like it was too close to the headers but it was definitely on top.
Guess ill give it a go... wish my hands were half the size.

Anyone know if my CEL will go away on its own after doing repairs or do the codes need to be cleared?

[imnuts]

What codes do you have, and what are you doing to try and fix them?

Got a bank 2 cat efficiency code. Throwing a spacer (minicat) on the downstream O2 sensor before emissions is due in a couple weeks. Gotta get rid of this CEL!

[imnuts]

Yeah, if you're putting a spacer in the second O2 sensor, that should allow you to clear the code and keep it away. Good luck

Thanks! All I have is a regular closed wrench, and an adjustable... Ill need the luck!
