Vacuum Switching Valve Inspection

Measure the VSV resistance.

Standard resistance:

Tester Connection	Specified Condition
1-2	37 to 44 Ω at 20°C (68°F)
1 - Body ground 2 - Body ground	10 kΩ or higher

Check VSV operation.

1. When vacuum is applied to the E port, check that air is sucked into the filter.
   If the result is not as specified, replace the VSV.
   





2. Apply battery voltage across the terminals. When vacuum is applied to the F port, check that air is sucked into the E port.
   If the result is not as specified, replace the VSV.
