Solution

1. Preparation

Gather tools and equipment including an OBD-II scanner, notebook for recording codes, and any necessary repair tools.
Ensure the vehicle is parked on a flat surface and the engine is off.

2. Read Diagnostic Trouble Codes

Connect the OBD-II scanner to the vehicle's diagnostic port, typically located under the dashboard.
Turn the ignition to the "ON" position without starting the engine.
Follow the scanner’s instructions to retrieve DTCs and record them for further analysis.

3. Address Identified Issues

Based on the retrieved codes, inspect the relevant components (e.g., oxygen sensors, mass airflow sensor, spark plugs).
Perform necessary repairs or replace faulty components as indicated by the codes.
Clear any additional fault codes that may arise during the repair process.

4. Clear Check Engine Light

With the OBD-II scanner still connected, navigate to the option to clear trouble codes.
Confirm the action to clear the codes, which resets the check engine light.
Disconnect the OBD-II scanner once the process is complete.

5. Test Drive

Start the engine and allow it to idle for a few minutes.
Take the vehicle for a short test drive, monitoring the dashboard and ensuring the check engine light remains off.
If the light re-illuminates, repeat diagnostic steps to identify any unresolved issues.
