1. Disconnect IACV-AAC valve harness connector.
2. Check resistance between the following terminals.
terminal 2 and terminals 1, 3
terminal 5 and terminals 4, 6

Resistance: Approximately 30 ohms [At 25°C (77°F)]




3. Reconnect IACV-AAC valve harness connector.
4. Remove idle air adjusting unit assembly (IACV-AAC valve is built-in) from engine.
(The IACV-AAC valve harness connector should remain connected.)
5. Turn ignition switch "ON" and "OFF", and ensure the IACV-AAC valve shaft smoothly moves forward and backward, according to the ignition switch position.
If NG, replace the IACV-ACC valve.
