1. INSPECT IDLE AIR CONTROL (IAC) VALVE FOR OPERATING SOUND.
- Check that there is a clicking sound immediately after stopping the engine.
- If operation is not as specified, check the IAC valve, wiring and ECM.





2. INSPECT IAC VALVE RESISTANCE.
- Using an ohmmeter, measure the resistance between the terminals (B1 (or B2) to others).

Resistance: 18 - 22 Ohms at 20°C (68°F)

- If the resistance is not as specified, replace the IAC valve.
