Abstract
Methods and systems for controlling and reducing current consumption of a vapor blocking valve are disclosed. In one example, current supplied to the vapor blocking valve is adjusted proportionately to fuel tank pressure to compensate for fuel tank pressure acting on the vapor blocking valve. Vapor blocking valve current is adjusted to reduce current consumption.
