VACUUM SWITCHING VALVE(for Engine Mounting) INSPECTION

PROCEDURE


  1. INSPECT VACUUM SWITCHING VALVE (for Active Control Engine Mount System)


    1. Measure the resistance.


      1. B004KR8C02
        *a

        Component without harness connected

        (Vacuum Switching Valve (for Active Control Engine Mount System))

        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) 37 to 44 Ω
        1 - Body ground 10 kΩ or higher
        2 - Body ground 10 kΩ or higher

        If the result is not as specified, replace the vacuum switching valve (for active control engine mount system).

    2. Check the operation of the vacuum switching valve (for active control engine mount system).


      1. B004OAVC01
        *a Port (F)

        Using a vacuum pump, apply a vacuum of 67 kPa (503 mmHg, 19.8 in. Hg) to port (F) and check that the vacuum is maintained.

        OK
        Vacuum pressure holds.

        If the result is not as specified, replace the vacuum switching valve (for active control engine mount system).

      2. B004N4VC01
        *a Port (E)
        *b Port (G)
        *c Air

        Check that air flows from port (E) to port (G).

        Standard
        Air flows from port (E) to port (G).

        If the result is not as specified, replace the vacuum switching valve (for active control engine mount system).

      3. B004KK6C01
        *a Port (E)
        *b Port (F)
        *c Air

        Apply battery voltage to the terminals and check that air flows from port (E) to port (F).

        Standard
        Air flows from port (E) to port (F).

        If the result is not as specified, replace the vacuum switching valve (for active control engine mount system).
