Question about 1998 Jeep Grand Cherokee
These are O2 sensor related problems and have changed both but the check engine light stays on. What to do next?
You said you changed the O2 sensors, which ones? I do believe that sensor 2 is the Catalyst efficiency monitor, it looks like an O2 but it's function is different. This sensor is behind the Catalytic converter, the O2 is in front. Bank one is the bank that # 1 cylinder is on, so the sensor that is defective is the 2nd sensor back on that sides exhaust pipe.
