Vacuum Regulating Valve Inspection

Inspect the VRV for an open circuit.

1. Measure the resistance between the terminals.
   

   Standard resistance:

   11.1 to 12.5 Ω at 20°C (68°F)
   

Inspect the VRV operation.

1. Check that air flows from port E to G.
   





2. Apply battery voltage across the terminals.
   

3. Check that air flows from port E to the filter.
