Final Test
WARNING: This page is about a different variant/trim than selected.
In event five all of the EVAP components return to the same state they were in event one. Because the vacuum pump remained ON in event four, the FTP sensor still detected a small vacuum. Now, with all components OFF, the pressure should return to atmosphere, indicating there are is no blockage or restrictions in the EVAP system.
