first off.. we need to know engine size and all that.. and i will see what i can find

 

You have 2 oxygen sensors. One is the "upstream" sensor and it is located on the rear exhaust manifold. Then you have the "downstream" sensor that is located on the exhaust pipe just behind the catalytic convertor. This way the computer can sense what is going into the convertor, and what is coming out.
