While oxygen sensor failure is a typical occurrence, the component may be replaced at home, saving you a significant repair expense. On a Jeep Wrangler, the oxygen sensors are located between the engine and the catalytic converter. To remove the oxygen sensor, you’ll need a specialized socket, which you can find at most auto parts and tool supply stores.
Steps
- Lift the Jeep with a jack and secure it with a set of jack stands on all four sides. Because the oxygen or O2 sensors are situated in the exhaust beneath the centre of the Jeep, accessing them properly requires elevating the entire vehicle.
- Two O2 sensors should be located in the exhaust system. One is located at the transmission’s center, while the other is located between the resonator and the catalytic converter. Unplug the wiring harness connectors from both sensors by raising the locking tab and drawing them free from the harness with a short flat screwdriver.
- Remove the oxygen sensors one at a time with a ratchet and an oxygen sensor socket. To remove the sensor from the exhaust, counterclockwise turn it. Remove the old sensor and dispose of it.
- Replace the two replacement sensors in the threaded parts of the exhaust where the old ones were removed. Jeep uses two identical sensors, which means that either one will work in each hole.
- Tighten the sensors to a torque of 22 foot-pounds using an oxygen sensor socket and torque wrench. On the threads of the sensor, never use thread locker, anti-seize, or any other substance.
- Connect both sensors’ wire harness connectors to the wiring harnesses plugs. Ascertain that they are securely fastened to the connector by visually inspecting the tab for engagement. Lower the Jeep to the ground using the jack stands. Run the engine for a few minutes and check to see whether the CEL or check engine light has gone off.

They should be sprayed with PB blaster or similar penetrating oil and then run through a few heat cycles. Your exhaust will smoke slightly as a result, but I had no difficulty removing any of them at 110k. I was able to remove mine using a common wrench, but depending on how well they are trapped, a specific socket or the appropriate size open end wrench would be a better option.
Those specialized 02 sensor sockets with the wiring cut carved into the side are frequently insufficient for extracting seized 02 sensors. That slot may weaken them sufficiently to prevent them from extracting a properly seized 02 sensor. For those, I just cut the wiring from the old 02 sensor and replace it with a standard 7/8″ “To dismantle it, use a wrench or socket. The new 02 sensor is then installed using the unique 02 sensor socket with the wiring slot. And, at times, removing older 02 sensors can be a real pain. I ended up welding an 18″ extension to a 7/8” open-end/box-end wrench to increase leverage for when they became totally stuck.
I opted for a lengthy 7/8 inch “multi-tool. To increase leverage while using a combo wrench with the box end on the item being removed, insert another box end wrench through the open end and secure it; this will double the length of the wrench. The leverage wrench will now be angled sideways as well, providing a flat surface for pressing with your palm.
