        Open the fuel tank cap again and check for inhalation sounds.

        OK
        No whooshing sounds (inhalation sound) are heard.

      6. Perform the "Activate the VSV for Evap Control" Active Test while the engine is idling.

      7. Close the fuel tank cap and allow the engine to idle for 30 seconds.
