Fuel Pressure Control Valve
ENGINE CONTROL COMPONENTS
Fuel Pressure Control Valve
The PCM controls the fuel rail pressure (FRP) by activating the fuel pressure control valve which regulates the fuel pressure at the outlet of the high
pressure fuel injection pump. Refer to the Fuel System, Fuel Pump System. The PCM regulates FRP by controlling the on/off time of the fuel pressure
control valve solenoid. An increase or decrease in the on/off lime positions maintains pressure in the fuel system or vents pressure to the fuel cooler. A
high duty cycle indicates a high FRP is being commanded. A low duty cycle indicates less pressure is being commanded. The fuel pressure control
valve is mounted on the top rear of the engine in the high pressure fuel injection pump cover and is integrated to the high pressure fuel injection pump.
