Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety while working on electrical components.

2. Replace Faulty Components

If error codes indicate a specific component failure (e.g., oxygen sensor, MAF sensor, spark plugs):

Oxygen Sensor Replacement:
1. Locate the oxygen sensor (upstream or downstream) based on the diagnostic code.
2. Use an oxygen sensor socket to unscrew the old sensor.
3. Apply anti-seize compound to the threads of the new sensor.
4. Install the new oxygen sensor and tighten to manufacturer torque specifications (usually 30 ft-lbs).
Spark Plug Replacement:
1. Remove the ignition coil or spark plug wires.
2. Use a spark plug socket to remove the old spark plugs.
3. Check the gap on the new spark plugs and adjust as necessary.
4. Install new spark plugs and tighten to manufacturer specifications (usually 13-15 ft-lbs).

3. Clear Error Codes

Reconnect the negative terminal of the battery.
Use the OBD-II scanner to clear the error codes from the system.
Start the engine and observe whether the check engine light remains off.

4. Final Checks

Perform a visual inspection for any remaining issues.
Make sure all electrical connections are secure and hoses are properly attached.
