Solution
1. Preparation
  • Gather necessary tools and parts.
  • Park the vehicle on a level surface and engage the parking brake.
  • Disconnect the negative battery terminal to ensure safety.
2. Inspect and Replace the Gas Cap
  • Sub-steps:
    • Remove the gas cap and inspect for damage.
    • If damaged, replace it with a new OEM gas cap.
    • Reattach the gas cap securely.
3. Inspect EVAP Hoses and Connections
  • Sub-steps:
    • Visually inspect all EVAP hoses connected to the fuel tank, charcoal canister, and purge valve.
    • Replace any cracked or damaged hoses with new hoses of the same diameter.
    • Ensure all connections are secure and properly seated.
4. Perform Smoke Test
  • Sub-steps:
    • Use a smoke machine to introduce smoke into the EVAP system.
    • Observe for smoke escaping from any component, including hoses, connectors, and the charcoal canister.
    • Seal any identified leaks by replacing the faulty component.
5. Inspect and Replace Purge and Vent Valves
  • Sub-steps:
    • Locate the purge valve and vent valve, typically found near the charcoal canister.
    • Disconnect the electrical connectors and vacuum hoses.
    • Test the valves for proper operation with a multimeter.
    • Replace any faulty valves with new ones if they do not operate as intended.
6. Reconnect Battery and Clear Codes
  • Sub-steps:
    • Reconnect the negative battery terminal.
    • Use the OBD-II scanner to clear any stored trouble codes.
    • Start the vehicle and allow it to run for a few minutes to check for any reoccurrence of the check engine light.
