Variable Induction Control Solenoid: Description and Operation

PURPOSE

The Vacuum Switching Valve (VSV) opens and closes the vacuum source to the Actuator, which in turn opens or closes the Intake Air Control
Valve.

OPERATION

The VSV is a two port vented vacuum solenoid. With no power applied, vacuum is shut off and atmospheric pressure is allowed to the Actuator.
When energized by the Engine Control Module vacuum passes through the VSV to the Actuator.
