VACUUM SWITCHING VALVE (w/ EGR Cooler) INSPECTION


  1. INSPECT NO. 1 VACUUM SWITCHING VALVE (for EGR Cut)


    1. A01E1FZE02

      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. A01E1E1E01

      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. A01DXALE01

        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.

  2. INSPECT NO. 2 VACUUM SWITCHING VALVE (for No. 2 EGR)


    1. A01DZYVE01

      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. A01DVMAE03

      Check operation of the VSV.


      1. 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.

      2. A01DZO7E01

        Apply battery voltage across terminals 1 and 2.

      3. Attach a vacuum pump to port E, and check that vacuum flows from port E to port F.

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