VACUUM SWITCHING VALVE INSPECTION


  1. INSPECT VACUUM SWITCHING VALVE ASSEMBLY


    1. A003I1OE07

      Measure the resistance of the VSV.

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 - 2 20°C (68°F) 37 to 44 Ω

      1 - Body Ground

      2 - Body Ground

      Always 10 kΩ or higher

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

    2. A003HAYE05

      Check operation of the VSV.


      1. Attach a vacuum pump to port E and check that vacuum does not flow from the filter to port E.

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

      2. A003AQFE04

        Apply battery voltage across terminals 1 and 2.

      3. Attach a vacuum pump to port E and check that vacuum flows from the filter to port E.

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