EGR BYPASS VALVE SWITCHING VALVE INSPECTION

PROCEDURE


  1. INSPECT NO. 1 VACUUM SWITCHING VALVE ASSEMBLY


    1. A01L82MC01
      *a

      Component without harness connected

      (No. 1 vacuum switching valve assembly)

      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) 33 to 39 Ω

      1 - Body ground

      2 - Body ground

      20°C (68°F) 1 MΩ or higher

      If the result is not as specified, replace the No. 1 vacuum switching valve assembly.

    2. Check operation of the No. 1 vacuum switching valve assembly.


      1. A01L983C01
        *a Vacuum
        *b Air
        *c Port E
        *d Port F
        *e Filter

        When a vacuum of 60 kPa (450 mmHg, 18 in.Hg) is applied to port F, check that air flows from port E to the filter.

      2. A01L8O4C01
        *a Air
        *b Port F
        *c Port E

        Apply battery voltage 12V 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 No. 1 vacuum switching valve assembly.
