Acoustic Control Induction System (ACIS): Inspection

1. With 39.9 kPa (300 mmHg, 11.8 in.Hg) of vacuum applied to the actuator, check that the actuator rod moves.
2. One minute after applying the vacuum in step (a), check that the actuator rod does not return.

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

1. Using an ohmmeter, check that there is continuity between each terminal.

   Resistance: 33 to 39 Ω at 20°C (68°F) 

   If there is no continuity, replace the VSV.
