Intake Air Control Valve: Inspection

1. With 26.7 kPa (200 mmHg, 7.9 in.Hg) of vacuum applied to the actuator, check that the actuator rod moves.
2. One minute after applying the vacuum, check that the actuator rod does not return.
3. If the operation is not as specified, replace the intake air control valve assembly No.2.

1. Inspect actuator operation
   1. With 26.7 kPa (200 mmHg, 7.9 in.Hg) of vacuum applied to the actuator, check that the actuator rod moves.
   2. One minute after applying the vacuum, check that the actuator rod does not return.
   3. If the operation is not as specified, replace the intake air control valve No.3.

2. Inspect VSV for continuity
   1. Using an ohmmeter, check for continuity between the terminals.

      Resistance: 

      37 to 44 Ωat 20°C (68°F) 

      If there is no continuity, replace the VSV.

   2. Inspect the VSV for ground.
      • Using an ohmmeter, check that there is no continuity between each terminal and the body.

      If there is continuity, replace the VSV.

   3. Inspect the VSV operation.
      • Check that air flows from port E to the filter.
      • Apply battery voltage across the terminals.
      • Check that air flows from port E to F.

If operation is not as specified, replace the VSV.
