93 book on AFM SFI system (T16Lamda)
Idle Air Control valve 272
The idle air control valve (AIC valve) is controlled with the aid of variations in current from the ECM. The ECM controls the degree of opening of the valve so that a controlled air flow is allowed past the throttle plate.
If a fault occurs in the valve, the valve is automatically adjusted down to a fixed idling speed = to 1200 rpm
You would have to use an ammeter to measure signal going to the AIC. Does it not work at all? Stick high idle?
