Solution

1. Preparation

Gather tools and equipment: OBD-II scanner, socket set, torque wrench, multimeter, replacement parts as needed.
Ensure the vehicle is parked on a flat surface and the engine is off before beginning work.

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.
Retrieve fault codes and write them down for reference.
Research the codes to understand the underlying issues.

3. Inspect and Replace Components

A. Gas Cap

Remove the gas cap and inspect for cracks or worn seals.
Replace the gas cap if necessary and ensure it clicks securely when refitted.

B. Spark Plugs and Ignition Coils

Remove the engine cover (if applicable) using a socket set.
Disconnect the ignition coils from the spark plugs.
Remove spark plugs using a spark plug socket and inspect for wear or fouling.
Replace any faulty spark plugs with OEM replacements, tightening to the manufacturer's specified torque (typically 15-20 ft-lbs).
Reinstall ignition coils and ensure they are seated properly.

4. Inspect for Vacuum Leaks

Visually inspect vacuum hoses and connections for cracks or disconnections.
Use a multimeter to check for electrical continuity in the hose connections.
Replace any damaged hoses and recheck the connections.

5. Reset the Check Engine Light

Use the OBD-II scanner to clear any fault codes after repairs are completed.
Turn off the ignition, disconnect the scanner, and start the engine to verify that the check engine light does not return.
