Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical shorts.
Allow the engine to cool before starting work.

2. Remove the Oxygen Sensor

Locate the upstream oxygen sensor (usually near the exhaust manifold).
Use an oxygen sensor socket or wrench to unscrew the sensor from the exhaust pipe.
Carefully disconnect the sensor's electrical connector.

3. Inspect and Replace

Inspect the old oxygen sensor for any signs of damage or contamination.
If the sensor is faulty, obtain a replacement oxygen sensor that meets OEM specifications.
Install the new oxygen sensor by reversing the removal steps, ensuring the connector is secure.

4. Reconnect the Battery

Reconnect the battery terminals, ensuring a secure connection.
Clear the trouble codes using the OBD-II scanner.

5. Final Checks

Start the engine and let it idle for a few minutes.
Check for any exhaust leaks around the new sensor and inspect for proper operation.
