VACUUM SWITCHING VALVE (w/o EGR Cooler) INSPECTION


  1. INSPECT VACUUM SWITCHING VALVE (for EGR Cut)


    1. A01E1FZE01

      Measure the resistance of the VSV.

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

      1 - Body Ground

      2 - Body Ground

      		 1 MΩ or higher

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

    2. A01DVLYE01

      Check operation of the VSV.


      1. Check that air dose not flow from port E to the filter.

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

      2. A01E29JE01

        Apply battery voltage across terminals 1 and 2.

      3. Check that air flows from port E to the filter.

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