Variable Induction Control Valve: Testing and Inspection

Shutter Valves (VICS):

1. Remove shutter valve actuator.
2. Verify that shutter valve rotates smoothly.
3. If valve is stuck or rotation is not smooth, check for possible obstructions and clean dynamic chamber and valve shaft.
4. If smooth operation cannot be obtained, replace dynamic chamber. Valve is not replaceable as a separate unit.
