Instructions
1. Locate the oxygen sensor. The oxygen sensor is located on the exhaust pipe, just before the catalytic converter.
2. Disconnect the electrical connector from the oxygen sensor.
3. Use the oxygen sensor socket to loosen the oxygen sensor from the exhaust pipe. If it doesn’t come loose with the socket, try spraying penetrating oil on it and letting it sit for a while before trying again.
4. Remove the oxygen sensor from the exhaust pipe.
5. Install the new oxygen sensor. Hand-tighten the oxygen sensor into the exhaust pipe, then tighten it with the oxygen sensor socket.
6. Connect the electrical connector to the oxygen sensor.
7. Start the engine and let it run for a few minutes. Check for any leaks from the oxygen sensor.
