ABSTRACT:
A method of testing an evaporative emission control system to determine if the evaporative emission control system has reached a predetermined pressure includes the steps of pulsing a leak detection pump at a predetermined rate and determining if a last pump period is greater than or equal to a predetermined test mode period threshold. The method also includes the steps of pressurizing the evaporative emission control system if the last pump period is less than a test mode period threshold and continuing the method if the last pump period is equal to or greater than the test mode period threshold.
