1. INSPECT VACUUM SWITCHING VALVE ASSEMBLY (for EVAP)

1. Measure the resistance of the switching valve.

   Standard:

     Tester Connection | Specified Condition
     1 - 2 | 26 to 30 Ω at 20°C (68°F)
     1 - Body Ground 2 - Body Ground | 10 MΩ or higher

   If the result is not as specified, replace the switching valve.

1. Check operation of the switching valve.

   1. Check that air does not flow from port E to port F.

   2. Apply battery voltage across terminals 1 and 2.

   3. Check that air flows from port E to port F.
      If the result is not as specified, replace the switching valve.
