Vacuum Switching Valve (VSV) for EGR: Testing and Inspection
EGR Vacuum Switching Valve (VSV) CA Only
VSV INSPECTION PROCEDURE
1. REMOVE THE VACUUM SWITCHING VALVE (VSV).
a. Disconnect the following connectors and hoses.
1. VSV for EGR (A) connector.
2. VSV for fuel pressure control connector.
3. Vacuum hose (from EGR valve) from port E of VSV (A).
4. Vacuum hose (from port Q of EGR vacuum modulator) from port G of VSV (A).
5. Vacuum hose (from fuel pressure regulator) from port E of VSV (B).
6. Vacuum hose (from air intake chamber) from port G of VSV (B).
b. Remove the bolt and the VSV assembly.
2. INSPECT THE VSV FOR AN OPEN CIRCUIT.
-
Using an ohmmeter, check that there is continuity between the terminals.
Resistance: 33 - 39 Ohms at 20°C (68°F)
-
If there is no continuity, replace the VSV.
3. INSPECT VSV FOR GROUND.
-
Using an ohmmeter. check that there is NO continuity between each terminal and the body.
