Recently pulled a PO137 error code from my 2000 XJ. Looked up the code and it tells me it is bank1 sensor2 low voltage. Since this is the downstream O2 sensor and my XJ has 74K on it I figured I would just change the sensor.
Went under the truck and found 4 sensors! Guess I have the CA emissions model. Can someone explain which sensor is the 1/2 sensor? I would guess it is one of the sensors after each precat, but is it right or left?
Thanks.
