Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, and basic hand tools.
Ensure the vehicle is parked on a level surface with the engine turned off.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port, usually located under the dashboard near the steering column.
Turn the ignition key to the "On" position without starting the engine.
Follow the scanner’s prompts to read the trouble codes and document any found codes.

3. Address Issues

Based on the codes retrieved, troubleshoot and repair the underlying issue (e.g., replace faulty sensors, repair hoses, etc.).
If no issues are found or if the gas cap was loose, ensure it is securely tightened or replaced if damaged.

4. Clear the Check Engine Light

With the OBD-II scanner still connected, navigate to the option to clear codes.
Confirm the action to clear all trouble codes stored in the vehicle’s system.

5. Final Checks

Disconnect the OBD-II scanner.
Start the engine and allow it to run for a few minutes to check if the check engine light remains off.
