1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery negative terminal to prevent electrical shorts.

2. Address Fault Codes

• Sub-step 1: Use the OBD-II scanner to retrieve stored fault codes.
• Sub-step 2: Refer to the Honda service manual to interpret the codes and identify the components involved.
• Sub-step 3: Clear the codes from the memory and see if they reappear after a test drive.

3. Inspect and Repair Components

• Sub-step 2: If issues with wiring or connectors are found, repair or replace damaged wiring and ensure all connections are secure.
• Sub-step 3: If the gas cap is faulty, replace it with a new OEM gas cap to ensure proper sealing.

4. Reconnect Components

• Sub-step 1: Reconnect the battery negative terminal after all repairs are complete.
• Sub-step 2: Start the engine and monitor for any warning lights or unusual behavior.

5. Final Inspection

• Sub-step 1: Perform a visual inspection of the engine bay for any signs of leaks or loose components.
• Sub-step 2: Take the vehicle for a test drive to confirm that the check engine light does not reappear.
