Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, vehicle jack and stands.
Parts Required: New O2 sensor (if necessary).
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Remove the Old O2 Sensor

Locate the O2 sensor (usually found in the exhaust manifold or just after the catalytic converter).
Use the socket set to carefully unscrew the O2 sensor from its mounting point.
Disconnect the electrical connector by pressing the release tab and pulling apart.

3. Install the New O2 Sensor

Apply anti-seize compound to the threads of the new O2 sensor (if not pre-applied).
Screw the new O2 sensor into the exhaust system and tighten it securely (typically 30-50 ft-lbs, check specific torque values for your model).
Reconnect the electrical connector until it clicks into place.

4. Reconnect Battery and Perform Reset

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any existing error codes from the vehicle's computer.
Start the engine and allow it to reach operating temperature.
