Vacuum Switching Valve Inspection

Measure the resistance of the purge VSV.

Standard resistance:

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

Check the operation of the purge VSV.

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 purge VSV.
   

   NOTICE:

   Do not apply the voltage above 16 V.
