Fuel Pressure Control Solenoid: Description and Operation
PURPOSE
The Fuel Pressure Control Vacuum Switching Valve (VSV) is used to raise fuel pressure during hot restart conditions.
OPERATION
During a hot restart, the Engine Control Module energizes the Fuel Pressure Control VSV which redirects the vacuum supply for the Fuel Pressure
Regulator to atmosphere. When the vacuum is vented, the Fuel Pressure Regulator raises fuel pressure.
