Fuel Volume Control Valve
The PCM regulates fuel volume by controlling the duty cycle of the fuel volume control valve. The fuel volume control valve is a normally open valve. A high duty cycle indicates low fuel volume is being admitted to the high pressure fuel injection pump or low pressure. A low duty cycle indicates high volume is being admitted to the high pressure fuel injection pump or high pressure. The fuel volume control valve is mounted on the high pressure fuel injection pump.
