Idle Speed/Throttle Actuator - Electronic: Testing and Inspection

Schematic View Of ACV Circuit:

AIR CONTROL VALVE (ACV) INSPECTION

1. Inspect ACV for open circuit

Inspection Of ACV:

Using an ohmmeter.check that there is continuity between the terminals.

Resistance: 30 - 33 Ohms at 20°C (68°F)

If there is no continuity.replace the ACV.

2. Inspect ACV for ground






Using an ohmmeter, check that there is no continuity between each terminal and body.

If there is continuity, replace the ACV.

3. Inspect ACV operation






a. Check that air does not flows from ports E to F.


b. Apply battery voltage across the terminals.








Check that air flows from ports E to F.

If operation is not as specified, replace the ACV.
