The Variable Induction Control (VIC) solenoid is an ON/OFF type of solenoid which switches the pressure introduced to the VIC vacuum actuator between intake manifold pressure and atmospheric pressure. Battery positive voltage is supplied to the VIC solenoid via the MFI relay. When the ECM turns the power transistor inside the module on, current flows in the solenoid coil and the negative pressure inside of the intake manifold is introduced to the VIC vacuum actuator. This causes the VIC vacuum actuator to operate and close the control solenoid.
The VIC solenoid is located next to the EGR valve on the engine.
