Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety.
Elevate the vehicle using a jack and secure it on jack stands if necessary.

2. Remove the Old Oxygen Sensor

Locate the oxygen sensor on the exhaust system (usually before the catalytic converter).
Use an oxygen sensor socket or a wrench to unscrew the oxygen sensor from its mounting point.
Carefully disconnect the wiring harness from the sensor.

3. Install the New Oxygen Sensor

Apply anti-seize compound to the threads of the new oxygen sensor (if not pre-applied).
Screw in the new oxygen sensor by hand to avoid cross-threading, then tighten it securely with the sensor socket.
Reconnect the wiring harness to the new oxygen sensor.

4. Reconnect Battery and Test

Reconnect the vehicle battery.
Start the engine and let it idle for a few minutes to ensure proper operation.
Check for any error codes using the OBD-II scanner and clear any existing codes.
