What is the purpose of a vacuum switching valve?
The vacuum switching valve (VSV) which controls the vacuum supply to the actuator is normally closed and passes vacuum to the actuator when it is energized by the ECU. By energizing the VSV vacuum is passed to the actuator, closing the air control valve. This effectively lengthens the intake manifold run.
What does a bimetal vacuum switching valve do?
Not only is it a mouthful of letters, it’s an important piece. This BVSV controls the vacuum to the EGR valve (it will not let vacuum flow through unless the coolant is at normal operating temp).
What are the symptoms of a bad EGR vacuum solenoid?
