      *a

      Component without harness connected

      (Electric Vacuum Regulating Valve)

      Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 - 2 20°C (68°F) 11 to 13 Ω

      1 - Body ground

      2 - Body ground

      		 20°C (68°F) 10 MΩ or higher

      If the result is not as specified, replace the electric EGR control valve assembly.

      *1 Port E
      *2 Port F
      *3 Vacuum
      *4 Air
      *5 Filter

      Check operation of the E-VRV.


      1. When a vacuum of 67 kPa (500 mmHg, 19.7 in.Hg) is applied to port F, check that air flows from port E to the filter.

        *1 Port E
        *2 Port F
        *3 Air

        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 electric EGR control valve assembly.
