Variable Induction System: Testing and Inspection

INSPECTION





1. Using a 3-way connector connect a vacuum gauge to the Acoustic Control Induction System (ACIS) Actuator hose.
2. Start the engine.
3. While the engine is idling, check that the vacuum gauge needle does not move.





4. Rapidly depress the accelerator pedal to the fully open position and check that the vacuum gauge needle momentarily fluctuates up to approximately 26.7 kPa (7.9 in Hg). Verify that the actuator rod is pulled out.
