Steps
Raise and disconnect the vehicle
Let the exhaust cool completely, then raise and support the vehicle on rated stands. Unplug the oxygen-sensor connector and free its wiring from retaining clips.
Remove the old sensor
Use a suitable sensor wrench to loosen the sensor from the exhaust bung. Remove it carefully and inspect the threads and surrounding pipe for damage.
Install the replacement sensor
Thread the replacement sensor by hand to avoid cross-threading, then tighten it to the vehicle specification. Reconnect the electrical plug and restore the wiring clips.
Lower and verify
Lower the vehicle and start the engine. Check for exhaust leaks near the sensor and confirm the wire stays clear of hot or moving components.
Check your vehicle’s repair manual for exact specifications and fit.
