Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Ensure the vehicle is parked on a level surface.
  • Disconnect the negative battery terminal to reset the ECU and prevent electrical shocks.
2. Inspect and Replace the Gas Cap
  • Remove the gas cap and inspect for cracks or wear.
  • If damaged, replace it with an OEM or equivalent gas cap.
  • Ensure the new cap is securely tightened after installation.
3. Check and Repair the EVAP System
  • Locate and inspect the EVAP canister and associated hoses for cracks or disconnected lines.
  • If any hoses are damaged, replace them.
  • Use a smoke machine to test for leaks within the EVAP system, sealing any detected leaks.

  • Use the OBD-II scanner to clear any stored trouble codes.
  • Start the engine to ensure the check engine light does not reappear.
