What is a VSV on a Toyota?

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 is VSV in car?

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. The valve is a normally closed (N/Q design which is opened when current is passed through the solenoid windings.

What is a VSV sensor?

The vapor pressure sensor is plumbed into the vapor pressure VSV, which is sometimes called the three-way VSV. One hose connects the VSV to the charcoal can- ister; another connects it to the fuel tank. When this VSV is electrically shut off, it connects the vapor pressure sensor to the canister.

What does a fuel vacuum switch do?

It’s used in many vacuum applications for pressure control purposes and safety interlock functionality. A multistage turbomolecular pumping system requires an adequate vacuum pressure level to operate and a vacuum switch can be used to control the pump and protect it from operating at too high pressure.

What is a EVAP VSV?

The EVAP control system is a system which utilizes the intake manifold vacuum to draw the evaporative emissions into the intake manifold and mix them with intake air. The ECM controls a duty–cycle type VSV (vacuum switching valve) to purge evaporative emissions from the charcoal canister.

Where is the EGR control valve located?

Answer: The purpose of the EGR valve is to recirculating engine exhaust gas to the back to the engine cylinders. To accomplish this task the EGR valve is attached to the intake manifold of the engine. This location is atop of the engine near the carburetor, usually towards the back of the engine near the firewall.
