INTAKE MANIFOLD INSPECTION

PROCEDURE


  1. INSPECT INTAKE MANIFOLD

    Note

    Do not adjust the adjusting screw or 2 actuator installation bolts.

    A01L90X

    1. A01LEYIC02
      *a Disconnect

      Disconnect the vacuum hose from the actuator.

    2. Check the operation of the swirl control valve.


      1. Check that the valve is fully opened under normal conditions.

      2. Connect a vacuum pump to the control valve. Check that the valve is fully closed when a negative pressure of 35 kPa (263 mmHg, 10 in.Hg) is applied.

      3. Leave it for 1 minute and check that the vacuum pump needle does not move.

        If the result is not as specified, replace the intake manifold.

  2. INSPECT VACUUM SWITCHING VALVE (for Swirl Control Valve)


    1. 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) 10 kΩ or higher

      If the result is not as specified, replace the intake manifold.

    2. A01L8S8C01
      *1 Port E
      *2 Filter
      B0068HS Airflow

      Check the operation according to the value(s) in the table below.


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

        If the result is not as specified, replace the intake manifold.

      2. A01SC37C01
        *1 Port E
        *2 Port F
        B0068HS Airflow

        Apply battery voltage across the terminals.

      3. Check that air flows from port E to port F.

        If the result is not as specified, replace the intake manifold.
