VARIABLE FRESH AIR DUCT (VFAD) SOLENOID VALVE CONSTRUCTION/OPERATION (13B-MSP (HIGH POWER))
• Composed of a solenoid coil, spring, plunger, and filter.
• When the solenoid coil is energized, the plunger is pulled back. Pulling the plunger back opens the passage between ports A and B. Due to this, BARO is applied to the actuator.
• Passage of port A is closed by the reaction force of the spring, and the passage between ports B and C is opened. Due to this, intake manifold vacuum is applied to the actuator.
