Vacuum Switching Valve (For Unleaded Gasoline Specification Vehicle) 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 2 - Body ground	10 MΩ or higher

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.
