if the car only uses 2 02 sensors it's the upstream 1, if it uses 3 it's the upstream in the same side of the engine that cylinder #1 is located so follow your ignwires to cyl#1 and it will be in that exhaust manifold

Thanks so much for the quick response. There are 3 sensors on my car. Followed your instructions & replaced the sensor! Now let's hope she passes the emission test!
