Steps
Raise and support the vehicle
Raise the vehicle at approved lift points and support it on jack stands. Remove the lower splash shield bolts and clips to access the downstream sensor.
Remove the old oxygen sensor
Unplug the gray sensor connector and free the wire from its bracket. Use a 22mm sensor socket to loosen and remove the sensor from the exhaust pipe.
Install the replacement sensor
Inspect the exhaust threads for damage and start the new sensor by hand to avoid cross-threading. Tighten it to the vehicle's specification with the sensor socket.
Route and connect the sensor lead
Route the wire through the original bracket without stretching, pinching, or contacting hot exhaust components. Reconnect the plug until its latch engages.
Reinstall shields and verify
Reinstall the splash shields with the correct left and right orientation and secure their bolts and clips. Start the engine and check for exhaust leaks or warning indicators.
Check your vehicle’s repair manual for exact specifications and fit.
