Vacuum Switching Valve (VSV) for Vapor Pressure Sensor: Testing and Inspection
VSV FOR VAPOR PRESSURE SENSOR INSPECTION
1. Remove VSV.
(a) Disconnect the connector and 3 EVAP hoses from the VSV.
(b) Remove the bolt and VSV.
2. Inspect VSV.
(a) Using an ohmmeter, check that there is continuity between the terminals.
Resistance: At 20°C (68°F): 37 - 44 ohm
If there is no continuity, replace the VSV.
(b) Using an ohmmeter, check that there is no continuity between each terminal and the body.
If there is continuity, replace the VSV.
(c) Check that air flows from ports E to P, and does not flow from ports E to F.
