Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, oxygen sensor socket.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool down before working on exhaust components.

2. Remove the Faulty Oxygen Sensor

Locate the oxygen sensor (usually found in the exhaust manifold or downstream).
Use the oxygen sensor socket to unscrew the sensor from its position.
Disconnect the electrical connector from the sensor.

3. Inspect and Clean

Inspect the threads and mounting surface for debris or damage.
Clean the sensor port on the exhaust system with a wire brush to ensure proper sealing for the new sensor.

4. Install New Oxygen Sensor

Install the new oxygen sensor by screwing it into place hand-tight, then use the torque wrench to tighten it to the manufacturer's specified torque (typically 30-40 lb-ft).
Reconnect the electrical connector to the new sensor.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and let it idle to ensure there are no leaks and the sensor is functioning properly.
