How to Change an Oxygen Sensor in a 1996 Jeep Cherokee
The oxygen sensor on your 1996 Jeep Cherokee helps regulate the fuel consumption and emissions. The sensor is threaded into the exhaust manifold and monitors the oxygen saturation in the trucks exhaust. The Cherokees computer adjusts the fuel-and-air mixture combusted in the engine based on the oxygen saturation. If your truck begins to burn a noticeably greater amount of fuel compared to its normal fuel consumption, buy a replacement oxygen sensor from an auto parts store and change it at home.
Instructions

Lift the front of the Cherokee with a jack until it sits high enough to fit jack stands underneath it for support. Place the jack stands under the frame rails just behind the front wheels. Lower the Cherokee so that it rests securely on the jack stands.
2Disconnect the electrical connection from the oxygen sensor. Remove the sensor with a wrench or oxygen sensor socket attached to a ratchet.
3Spread a thin layer of anti-seize compound on the threads of the new sensor. Do not get anti-seize compound on the sensor head. Thread it into place by hand. Tighten the sensor with a wrench or a socket and ratchet.
4Connect the wiring harness connection by pressing it together until it clicks. Lift the truck with the jack until you can remove the jack stands. Return the truck to the ground.
