Control Devices
• The 6.4L Power Stroke
®
Diesel uses eight (8) control
devices: Pressure Control Valve, Volume Control Valve,
EGR Valve, Turbocharger Actuator, Glow Plug Control
Module, Glow Plugs, Fuel Injectors, and the Throttle Body.
PCV (Pressure Control Valve)
• The PCV governs the fuel pressure that is
delivered to the fuel injectors via the high
pressure fuel rails and fuel supply tubes.
• The PCV also acts as a dampening device for the
fluctuations in pressure that occur during fuel delivery
through the pump and the injection process.
• The PCV is controlled by the ECM to maintain optimal fuel
pressure throughout all engine operating conditions.
• The PCV is permanently mounted to the high
pressure pump and is not to be removed.
Removal of the PCV will result in replacement
of the high pressure fuel injection pump.
NOTE: Fuel caps have been left off for visualization
purposes. Always use fuel caps when
servicing the high pressure fuel system!
VCV (Volume Control Valve)
• The VCV regulates the delivery of fuel from the internal
transfer pump (ITP) to the high pressure pumping elements.
• The VCV adjusts the low pressure side of the system to
match the needs of the engine thus increasing efficiency.
• The VCV is permanently mounted to the high
pressure pump and is not to be removed.
Removal of the VCV will result in replacement
of the high pressure fuel injection pump.
NOTE: Fuel caps have been left off for visualization
purposes. Always use fuel caps when
servicing the high pressure fuel system!
