Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent any electrical issues during repairs.

2. Retrieve and Analyze Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "on" position without starting the engine.
Retrieve the error codes and record them for analysis.

3. Address Specific Codes

Based on the error codes retrieved:
- If the code is related to the oxygen sensor, replace the faulty sensor.
- For misfire codes, inspect and possibly replace spark plugs and ignition coils.
- If the code indicates a fuel system issue, check the fuel pump and filters.
Replace any damaged components as indicated by the diagnostic codes.

4. Clear Codes

After repairs are completed, use the OBD-II scanner to clear the error codes from the vehicle's computer.
Reconnect the battery.

5. Test Drive

Start the engine and allow it to idle for a few minutes.
Take the vehicle for a test drive to ensure the check engine light remains off and monitor performance.
