INTAKE MANIFOLD INSPECTION


  1. INSPECT INTAKE AIR CONTROL VALVE (for ACIS)


    1. Inspect the diaphragm.


      1. A01G6BME01

        Using a vacuum pump, apply a vacuum of 60 kPa (450 mmHg, 17.7 in.Hg) or higher to the diaphragm chamber. Wait for 1 minute and check that the needle of the vacuum pump does not lower.

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

    2. After applying vacuum in the step above, check that the actuator rod operates.

  2. INSPECT VACUUM TANK AND NO. 1 CHECK VALVE


    1. A01G5AO

      Disconnect the vacuum hose from the No. 1 check valve.

    2. Using a vacuum pump, apply vacuum to the No. 1 check valve. Wait for 1 minute and check that the needle of the vacuum pump does not lower.

      If the result is not as specified, replace the No. 1 check valve.

    3. Connect the vacuum hose to the No. 1 check valve.

    4. A01G80F

      Using a vacuum pump, apply a vacuum of 60 kPa (450 mmHg, 17.7 in.Hg) or higher to the vacuum tank. Wait for 1 minute and check that the needle of the vacuum pump does not lower.

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