Fit In Five Steps
How to replace a Subaru O2 Oxygen Sensor?
1.Locate Oxygen Sensor
Locate the oxygen sensor on your vehicle by looking for a part that looks like a spark plug that sticks out from the exhaust pipe. It will have an electrical connection attached to it.
2.Disconnect Connection
Disconnect the electrical connection on the oxygen sensor. Use a flat tip screwdriver to push in the tabs and pull the connection apart.
3.Remove Old Oxygen Sensor
Unscrew the oxygen sensor off the exhaust pipe using either an open-end wrench or a special socket made to remove it. The majority of oxygen sensors will take an SAE 7⁄8 inch (2.2 cm) wrench. If the new one did not come with an electrical connection, but just with the wires stubbed out, you need to do a little work.
- Cut off the old connector from the bad oxygen sensor, strip the wires and solder the wires to the new oxygen sensor. You can also use butt connectors.
- Use heat sensitive shrink tape to seal the connections.
- Follow manufacturer’s instructions to know which wires to tie together.
4.Install New Oxygen Sensor
Reverse the steps used in removing the oxygen sensor and install the new part. Add a small amount of anti-seize to the threads of the new sensor. Screw it in place clockwise and snug it down with the socket or open-end wrench. Do not over tighten the sensor as you might strip the threads.
5.Reconnect Wires & Check for Emission
Plug the electrical connections back in. Turn on the ignition key, but do not start your vehicle. Use the diagnostic scanner/reader to clear the code from the vehicle’s computer. Start the car. You should notice an immediate improvement.
