INTAKE SYSTEM ON-VEHICLE INSPECTION

PROCEDURE


  1. INSPECT INTAKE SYSTEM

    Tech Tips

    Perform "Inspection After Repair" after repairing vacuum leaks in the intake system.



    1. Check that there are no vacuum leaks at the points shown in the illustration.


      1. for LHD:

        B00670D

      2. for RHD:

        B0065FB

  2. PERFORM INITIALIZATION


    1. Perform "Inspection After Repair" after repairing vacuum leaks in the intake system.


  3. INSPECT INTAKE AIR CONTROL VALVE ACTUATOR


    1. B0067JR

      Disconnect the vacuum hose.

    2. B0065BDC01
      *a Vacuum applied
      *b Vacuum released
      *c Valve

      Confirm that the intake air control valve closes smoothly under vacuum and opens smoothly when the vacuum is released.

      If the intake air control valve does not close or open smoothly, replace the air cleaner assembly.

    3. Connect the vacuum hose.

  4. INSPECT NO. 1 VACUUM SWITCHING VALVE ASSEMBLY


    1. B0065S5

      Disconnect the No. 1 vacuum switching valve assembly connector.

    2. Disconnect the 2 vacuum hoses from the No. 1 vacuum switching valve assembly.

    3. B0066N8C01
      *a Body Ground

      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 Always 10 kΩ or higher
      2 - Body ground Always 10 kΩ or higher

      If the result is not as specified, replace the air cleaner assembly.

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


      1. B0066SPC01
        *a Filter
        *b Port (E)
        *c Air

        When vacuum is applied to the port (E), check that air is sucked into the filter.

        If air is not sucked into the filter, replace the air cleaner assembly.

      2. B006627C01
        *a Port (E)
        *b Port (F)
        *c Air

        Apply battery voltage across the terminals. When vacuum is applied to the port (F), check that air is sucked into the port (E).

        If air is not sucked into the port (F), replace the air cleaner assembly.
