Solution

1. Preparation

Tools Needed: OBD-II scanner, multimeter, socket set, torque wrench, oxygen sensor removal tool.
Disconnect the vehicle battery to ensure safety while working on electrical components.
Allow the engine to cool down before starting any work.

2. Remove the Faulty Oxygen Sensor

Locate the faulty oxygen sensor, typically found in the exhaust manifold or exhaust pipe.
Use the oxygen sensor removal tool to unscrew the sensor from its mounting.
Carefully disconnect the electrical connector from the oxygen sensor.

3. Inspect and Clean the Area

Inspect the sensor mounting location for any debris or carbon buildup.
Clean the threads of the exhaust pipe using a wire brush to ensure a proper seal for the new sensor.

4. Install the New Oxygen Sensor

Apply anti-seize compound to the threads of the new oxygen sensor (if required).
Screw the new oxygen sensor into place using the oxygen sensor removal tool; do not overtighten (usually 30-40 ft-lbs torque).
Reconnect the electrical connector to the new oxygen sensor.

5. Reconnect Battery and Test

Reconnect the vehicle battery.
Start the engine and let it run for a few minutes to check for any error codes or issues.
