The oxygen sensors on your Jeep metre the immensity of O2 to fuel burning and communicate to the pc of the Jeep when there is a variance of opulent or slim compound. After a while, due to heat and hour, the sensors breach down and desideratum to be replaced. Thanks to your Jeep may chalk up multiple O2 sensors, telling which one it is and where it is Testament be up to you. Statute readers can corrective decide a pathetic O2 sensor and its residence after it has tripped the engine pc and open the "research engine" brilliance. You'll essential a sporadic matters to install one yourself, so corner the parts store nourishment you absent in locating the good sensor and they'll most viable cook it for autonomous provided you get the parts from them.
Instructions
1. Deposit on the safety glasses and fix the O2 sensor(s) that require to be replaced. Most Jeeps Testament own the authentic 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 operation, again screwed into the exhaust pipes near the back of the manifold and near the catalytic converter. Whether you're on the ground under the Jeep and enjoy a creeper, grab the tools and crawl under.
2. Come from the wire attached to the O2 sensor to the plug. 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.
It's not going to be clear. 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 further, 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. Press the clip lock in with a screwdriver and seperate the O2 sensor wire from the plug.3. Put the wire of the O2 sensor finished the slot on the side of the oxygen sensor socket and dwelling the socket onto the sensor. Attach the ratchet and go to loosen it from the manifold or exhaust main.
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. 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.
