Solution

1. Preparation

Gather tools and materials: OBD-II scanner, socket set, replacement fuel cap (if necessary).
Park the vehicle on a level surface and engage the parking brake.

2. Retrieve and Analyze Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Follow the scanner's instructions to retrieve any stored trouble codes.
Note down the codes for further analysis.

3. Address Common Issues

Fuel Cap Inspection

Remove the fuel cap and inspect for cracks or wear.
If damaged, replace with a new fuel cap and ensure it is tightened securely.

Oil Level Check

Open the hood and locate the dipstick.
Remove the dipstick, wipe it clean, reinsert, and remove again to check oil level.
If low, add the appropriate oil type as specified in the owner's manual.

Air Filter Inspection

Locate the air filter housing and remove the cover (typically held by clips or screws).
Remove the air filter and inspect for dirt and blockage.
Replace the air filter if it appears excessively dirty or clogged.

4. Clear Error Codes

After addressing any issues, use the OBD-II scanner to clear the error codes.
Turn the ignition off and then back on to ensure the check engine light remains off.
