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