What does a Toyota vacuum switching valve do?
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.
Where is the vacuum switching valve on a Camry?
The Vacuum Switching Valve (VSV) is typically located on the engine (often under the intake manifold) or in the engine compartment, controlling a fixed air bleed into the intake manifold.
How much does it cost to replace a vacuum switching valve?

What does a vacuum switch valve solenoid do?
Vacuum solenoid valves are used to control actuators, in most cases connected with the emission system.
What does a vacuum valve do on a car?
Vacuum valves are operated inside machinery that use gauges and switches to control the flow of air or pressure inside the valve and release the pressure when needed for its application.
What is vacuum valve?
A vacuum valve is a device placed in a feed or vent line on a vacuum furnace whose purpose is to isolate the vacuum chamber or direct the flow of gas into the vacuum vessel. These valves can be actuated manually, pneumatically, electropneumatically, electrically or electromagnetically.

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 is a vacuum actuator?
A vacuum actuator is a mechanism that supplies a switching or activation force to a secondary device via the vacuum-induced movement of an internal piston or diaphragm. These actuators are typically found on machinery or processes that produce vacuums during operation, such as automobile engines.
What are the symptoms of a vacuum leak in a car?
Symptoms of a vacuum leak include the Check Engine light, rough idle, stalling and a hissing sound coming from the engine bay. The engine may run well at higher RPMs, but surges, runs rough and struggles to maintain stable RPMs at idle. Often, the engine stalls when stopping.

What does the VSV valve do on a 1998 Toyota Camry?
The vacuum switching valve (VSV) is a part of the exhaust gas recirculation (EGR) system of the 1998 Toyota Camry. The VSV is connected to the EGR valve. The function of the EGR system is to recirculate exhaust gases to the intake manifold of the engine and thereby reduce the nitrous oxide emissions of the vehicle (References 1).
