VSV For Pressure Switching Valve
VSV For Pressure Switching Valve1. REMOVE VSV
2. INSPECT VSV FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the terminals.
Resistance
At 20 °C (68 °F) 37 - 44 Ohms
At 120 °C (248 °F) 51 - 62 Ohms
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.
If there is continuity, replace the VSV.
4. INSPECT VSV OPERATION
a. Check that air does not flow from ports E to F.
b. Apply battery positive voltage across the terminals.
c. Check that air flows from ports E to F.
If operation is not as specified, replace the VSV.
