Q: How to Maintain an Oxygen Sensor on 2004 Jeep Grand Cherokee?
A: In order to service the oxygen sensor, make sure that the engine is cold. Lift the vehicle, pull the O 2S pigtail harness out, and pull the sensor out with a removal tool. Install the new sensor with no anti-seize attached, tighten it to 30 N.m, reattach the harness, and lower the car.
