How do you test a VSV valve?
Before you purchase the VSV, there is a way to test yours if you can get your hands on it. Supply power to the VSV, such as using a 9V battery, + to one of the electrical connector, and – to the other. You should hear a click sound on a working VSV.
What is a vacuum switching valve 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. The VSV allows only a small amount of air to by-pass the closed throttle valve when it is open, increasing engine speed by about 100 rpm when energized.
How do you know if the vacuum switching valve on a 1998?
Blow test. Remove the vacuum hoses from ports E and G. Blow air into port E and check that it comes out at port G. If it does not, the VSV is bad. Apply voltage and blow air. Apply battery voltage across the VSV terminals using wires from the battery terminals. Blow air into port E and see if it comes out of port F.
How does the vacuum switching valve on a 1998 Camry work?
by Walt Sampson. 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).
How do you remove a check valve on a vacuum?
Removing the check valve can sometimes be as easy as using the twist and pull method. If it is really stuck, spray a little penetrating oil between the vacuum brake booster check valve and the rubber sealing grommet.
How is the VSV connected to the EGR valve?
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). Detecting a bad VSV is difficult, but can be accomplished after completing a few tests.
Which is vacuum valve technology does Mitsubishi Electric use?
Applying Mitsubishi Electric’s conventional vacuum valve technology as the basis, arc control technology and insulation design are leveraged to reduce size even further (i.e., 84% compared to conventional products) and increase reliability (E2 class).
