What does a VSV valve do?
What does the 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.
Where is the VSV valve located?
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.
How do you check Toyota VSV?
Remove the electrical connector from the VSV and check the resistance across the terminals using an ohmmeter. The resistance should be 33 to 39 ohms (at an air temperature of 68 degrees). Resistance outside this range indicates that the VSV is bad (References 1).
How do you test VSV evaporation?
To test the Bypass VSV, disconnect the canister side line to the valve and monitor VPS signal while applying vacuum or low pressure from the EVAP tester to the line with the valve commanded open. The VPS should read the change. With the valve commanded closed, no change should be seen.
What does VSV stand for Toyota?
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 is VSV EVAP?
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.
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.
Does Toyota Corolla have EGR valve?
A Toyota Corolla EGR valve replacement from AutoZone ensures that your vehicle continues to operate smoothly and efficiently since a clogged valve is capable of causing engine failure.
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.

Where is the EGR valve located on a Toyota Corolla?
The EGR valve is located in the engine compartment (underneath the hood).
