Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a flat surface with the engine off.
Disconnect the battery to reset the vehicle’s computer.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port, typically located under the dashboard near the steering column.
Turn the ignition to the "ON" position without starting the engine.
Follow the scanner's prompts to retrieve error codes and document them.

3. Address Identified Issues

Based on the retrieved codes, perform necessary repairs or maintenance on components such as sensors, spark plugs, or fuel injectors as indicated by the codes.
Tighten or replace the gas cap if it was found to be the issue.

4. Clear Error Codes

With the OBD-II scanner still connected, navigate to the option to clear or erase codes.
Confirm the action and wait for the scanner to indicate that codes have been cleared.

5. Reconnect Battery

Reconnect the battery terminals, ensuring they are secure.
Turn the ignition back to the "ON" position and check if the check engine light remains off.

6. Test Drive

Take the vehicle for a short test drive to ensure the engine operates smoothly and the check engine light does not reappear.
