Hi,

I have read the stickies and I'm ready to replace my rear oxygen sensor (after getting the code). I haven't yet bought the rear sensor and I wanted to take a look under the car before I bought it.

I've located the sensor and the bolt is just to rusted. I'll have to try again tomorrow with PB blaster as recommended and let it soak.

Here's my question, how do I disconnect/remove the wires? I traced the wires that comes out of the rear heated sensor and I don't see any harness that I can pull, instead it goes into a little drilled hole...and I don't think you pull the wires out of the sensor itself.

I'm guessing that when I buy the rear sensor it come with a wire that leads to a wire harness that I would simply connect...just don't know where it connect to?..or at least I'm not seeing it.

Thank Guys.

The "little drilled hole" should be a hole in a rubber grommet. Pull that grommet out of the floor pan (from below) and the harness connector should be on the other side of it.

Never done it myself, but that's what the manual says.

It might help to warm the car up, and try to get the sensor out when it's hot. Of course, you want to be careful not to burn yourself.

Thanks. That's worked..my only other problem is how do I put it back? The little round rubbery-thingy won't stick back. Do I just put some silicone on it?
