VARIABLE BOOST CONTROL (VBC) SOLENOID VALVE CONSTRUCTION/OPERATION [MZR-CD (RF Turbo)]

id0113f1151000

## Construction

• Consists of the solenoid coil, spring, and plunger.

## Operation

Energized
• The solenoid coil magnetizes, pulling the plunger. The passage between B and C ports opens due to the plunger being pulled, and vacuum is applied to the actuator.
Non-energized
• The vacuum passage is blocked, and the passage between ports A and B opens, depressurizing the actuator.

1 | Port A (to vacuum chamber)
2 | Port B (to guide blade actuator)
3 | Port C (to atmospheric air)
