IDLE AIR CONTROL (IAC) VALVE
ON−VEHICLE INSPECTION
1. INSPECT IAC VALVE FOR OPERATING SOUND
Check that there is a clicking sound immediately after stopping
the engine.
If the operation is not as specified, check the IAC valve, wiring
and ECM.
2. INSPECT IAC VALVE RESISTANCE
(a) Disconnect the IAC valve connector.
(b) Using an ohmmeter, measure the resistance between the
terminals (B1 −S1 and S3, B2−S2 and S4).
Resistance:
At Cold: −10 − 50°C (−50 − 122°F): 15 − 25 Ω
At Hot: 50 −100°C (122 − 212° F): 20 − 30 Ω
If resistance is not as specified, replace the IAC valve.
(c) Reconnect the IAC valve connector.
