Zusammenfassung:1. Field of the Invention A method for actuating an onboard refueling vapor recovery (ORVR) valve to selectively enable passage of fuel vapor from a fuel tank to a collection canister for the fuel vapor. The method includes determining whether a filling event is occurring and determining a fuel level within the fuel tank. The ORVR valve is selectively opened and closed in connection with whether a fueling event occurs and whether the fuel tank is full.
