Solution

1. Preparation

Gather tools: OBD-II scanner, safety gloves, and safety glasses.
Ensure the vehicle is parked on a level surface with the engine turned off.

2. Scan for Error Codes

Plug the OBD-II scanner into the vehicle's OBD-II port, located under the dashboard on the driver's side.
Turn the ignition key to the "ON" position without starting the engine.
Follow the scanner's instructions to read and record any error codes.

3. Address Identified Issues

If any error codes are present, diagnose and repair the underlying issues before clearing the codes. Common repairs may include:
- Replacing faulty sensors (e.g., oxygen sensor, mass airflow sensor).
- Fixing vacuum leaks or exhaust leaks.
- Addressing ignition or fuel delivery problems.

4. Clear the Error Codes

With the OBD-II scanner still connected, navigate to the "Erase Codes" or "Clear Codes" function on the scanner.
Confirm the action and wait for the scanner to indicate that the codes have been successfully cleared.

5. Verify the Repair

Disconnect the OBD-II scanner.
Start the engine and allow it to idle for a few minutes.
Check to ensure the Check Engine Light remains off.
