Methods and systems are provided for expediting the generation of positive pressure and vacuum during corresponding phases of a fuel system leak test. Adjustments to the settings of active grille shutters and air dams enables heat to be trapped in the vehicle for the pressure phase and a cooling air flow to be provided during a vacuum phase. The adjustments enable the response time and completion frequency of an EONV test to be improved.
