Vacuum Switching Valve (VSV) for Vapor Pressure Sensor: Testing and Inspection
VACUUM SWITCHING VALVE FOR VAPOR PRESSURE SENSOR INSPECTION
1. Remove VSV
2. Inspect VSV
A. Inspect VSV for 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.
B. Inspect VSV for ground
Using an ohmmeter. check that there is no continuity between each terminal and the body.
If there is continuity. replace the VSV.
C. Inspect VSV operation
(a) Check that the air flows from ports E to G.
(b) Apply battery positive voltage across the terminals.
(c) Check that the air flows from ports E to F.
