I had my car scanned and my rear passenger side O2 sensor is going bad. Is this one easy to get to? Also, what does the sensor look like? Is it the boxed 4 pin connector or is it a flat 4 pin connector? Thanks for the help!

I wanna say it's flat and it looks like any other O2 sensor. Checkhere It might help to identify it correctly.

 

Thanks a lot. That was what I was looking for. The flat one is the front, the rear are the square.

 

Mine is a 94 so it only has 2, that's why I figured they were flat. Glad to help, that's why we're all here.

 

...hello!
So whats the easiest/quickest way to wire my air/fuel guage to my passenger side 02? I havnt taken a look under the car in awhile since my jack is gone! Arghh.

Thanks!

 

I don't know the answer to that, but you should start a new thread with that question. You will get better response. You can find the wires in the harness near your PCM.
