I posted earlier about my O2 sensor causing the check engine light to come on, and looking at the Haynes manual and other CEGer's advice it looks like something I can do this weekend.
Anyways when looking at the code list I see next to my code: P0153-Upstream Heated Oxygen Sensor circuit Slow Response - Bank No. 2. Does this mean that I only need to replace one of the O2 sensors?
If so which one is it the front or the back? Any help would be greatly appreciated. TIA.
