The present invention is an on-board refueling vapor recovery system for a motor vehicle comprising a fuel tank constructed to store a quantity of liquid fuel. A nozzle-receiving portion has a nozzle-receiving opening fluidly communicated with the fuel tank. Closure structure is constructed to be moved into closing engagement with the nozzle-receiving portion to close the nozzle-receiving opening. An exhaust passage communicates the fuel tank to an atmosphere outside of the motor vehicle to thereby allow fuel vapor to vent from the fuel tank to the atmosphere. The exhaust passage includes a filtration device communicated with the fuel tank to filter environmentally harmful elements from the fuel vapor as it vents from the fuel tank to the atmosphere. A closure structure sensing device is configured to transmit electric signals based on whether the closure structure is in closing engagement with the nozzle-receiving portion. A valve control unit is configured to control whether the valve is opened or closed. The control unit is responsive to the electric signal from the closure sensing device and to a signal from the motor vehicle indicating whether the motor vehicle ignition has been activated. The valve control unit opens the valve to communicate the fuel tank with the filtration device to thereby allow the fuel vapor to be filtered and vented from the fuel tank to the atmosphere through the exhaust passage in response to the signal indicating that the motor vehicle ignition has not been activated in combination with the electrical signal from the closure structure sensing device indicating that the closure structure has been moved out of closing engagement with the nozzle-receiving portion. The valve control unit closes the valve to prevent communication between the fuel tank and the filtration device in response to the signal that the motor vehicle ignition has been activated.
