Abstract
Methods and systems for controlling a fuel tank isolation valve coupled to a fuel tank in a vehicle are disclosed. In one example approach, a method comprises, in response to a refuel request, actuating a fuel tank isolation valve to vent a fuel tank for refueling; and, in response to a pressure in the fuel tank below a threshold pressure after a predetermined time duration, discontinuing actuation of the fuel tank isolation valve to seal the fuel tank.
