How to Properly Service an Oxygen Sensor on Jeep Grand Cherokee?

Ensure the oxygen sensor is serviced with caution, don't apply grease to the electrical connector and don't solder the wires of the oxygen sensor harness because this sensor needs a supply of outside oxygen through its pigtail wiring harness. Before you begin, let the exhaust manifold, exhaust pipes and catalytic converter(s) cool, because they get very hot while the engine runs. Bring the vehicle up, then separate the O2S pigtail harness from the main wiring harness and, if there are, disconnect the sensor wire harness clips mounted on the engine or body, making sure not to hold the wire tightly as you do this. You need a special O2S sensor removal and installation tool to do the job. New oxygen sensors are applied with anti-seize substance straight from the factory, so no more should be put on. After installing the O2S sensor, tighten it to 30 Nm (22 ft. lbs.); then, attach the O2S sensor wire connector to the main wiring harness. Once you have the tool, reattach the sensor wire clips to the engine or body, attach the O2S pigtail harness to its original places so it cannot be damaged and after everything is in place, lower the vehicle.

How to Maintain the Oxygen Sensor on a 2.4L Engine on Jeep Wrangler?

Be sure to wait until the engine has cooled before servicing the oxygen sensor, because these parts of the exhaust system become extremely hot while you drive. First, lift and secure the vehicle, then isolate the wire connector from the O2S sensor, always making sure not to tug straight on the cable leading to it. You should use the special tool for removing the sensor to take out the O2S and follow that with cleaning the exhaust threads by using an appropriate sized tap. Remember that the new O2S is factory coated with anti-seize compound, so do not add any further coating. Place the O2S sensor, secure it at 30 N.m (22 ft.lbs.) tightness and reconnect its wire and then drop the vehicle to the ground.
