The oxygen sensors on your Jeep metre the immensity of O2 to fuel burning and communicate to the machine of the Jeep when there is a variance of prosperous or lank brew. After a while, due to heat and time, the sensors hole down and duty to be replaced. By reason of your Jeep may bear multiple O2 sensors, telling which one it is and where it is Testament be up to you. Decree readers can helping hand halt a defective O2 sensor and its stop after it has tripped the engine pc and commence the "proof engine" brilliant. You'll want a meagre matters to install one yourself, so include the parts store assist you absent in locating the hold up sensor and they'll most possible cause it for cuffo provided you purchase the parts from them.
Instructions
The computer will have to go through a series of the Jeep heating itself up to normal operating temperatures and cooling down in order to run through the IM monitors. It can take up to a few days or so many miles traveled to do so. Whether you're on the ground under the Jeep and annex a creeper, grab the tools and crawl under.
2. Replace the wire attached to the oxygen sensor to the plug. Press the clip lock in with a screwdriver and seperate the O2 sensor wire from the plug.
3. Distance the wire of the O2 sensor nailed down the slot on the side of the O2 sensor socket and put the socket onto the sensor. Attach the ratchet and effort to loosen it from the manifold or exhaust drainpipe. It's not going to be accessible. You may have to heat up the exhaust pipe or manifold around the threads of the oxygen sensor with the torch. Only heat up the threads on the pipe or manifold because if you heat the oxygen sensor also, the metal in the sensor will expand along with the metal in the threads of the pipe and you will defeat the purpose. When the threads are nice and red, quickly apply the ratchet and socket and try to loosen it again. Once you're successful, allow the area that was heated up with the torch ample time to cool down.
4. Make sure there is a light coating of anti-seize lubricant compound on the threads of the new oxygen sensor. Most come with a light coating on them already. This will make future extractions easier. Screw the new sensor into the threads of the pipe by hand and be careful not to crossthread. Tighten the sensor with the ratchet and oxygen sensor socket. Do not over-tighten. There are only 4 to 5 threads on the oxygen sensors and although they need to be tight, over-tightening them can easily strip the threads of the sensor.
5. Plug the wire of the sensor back into the harness plug. Grab the tools and put them away. Start up the Jeep to make sure there is no exhaust leak coming from the oxygen sensor connection. To reset the "check engine" code, you can either wait it out for the Jeep to reset itself or take it back to the parts store and have them reset it.1. Levy on the safety glasses and set the O2 sensor(s) that call for to be replaced. Most Jeeps Testament posses the extremely front oxygen sensor screwed into the manifold on the Chauffeur's side of the engine that can be accessed from the engine compartment. The other ones Testament be located in the exhaust step, again screwed into the exhaust pipes near the back of the manifold and near the catalytic converter.
