Solution
1. Preparation
  • Gather tools and parts needed.
  • Disconnect the battery to ensure safety while working on electrical components.
2. Address Error Codes
  • Connect the OBD-II scanner to the vehicle's diagnostic port.
  • Record any trouble codes and research their meanings.
  • Clear the codes and perform a test drive to see if the light returns.
3. Check and Replace Faulty Components

a. Inspect and Replace Gas Cap

  • Remove the gas cap.
  • Inspect for cracks or wear; replace if necessary.
  • Reinstall and ensure it clicks securely.

b. Replace Spark Plugs and Ignition Coils (if indicated)

  • Remove engine cover (if applicable).
  • Disconnect ignition coil connectors.
  • Remove ignition coils using a socket set.
  • Replace spark plugs using a spark plug socket, ensuring correct torque (typically 12-15 ft-lbs).
  • Reinstall ignition coils and connect the connectors.

c. Repair Vacuum Leaks

  • Inspect all vacuum hoses for cracks or disconnections.
  • Replace any damaged hoses with appropriate replacements.
  • Ensure all connections are tight.

d. Test and Replace Fuel System Components

  • Connect a fuel pressure gauge to the fuel rail.
  • Turn on the ignition (do not start the engine) and check pressure.
