Idle Speed/Throttle Actuator - Electronic: Description and Operation

IACV-Auxiliary Air Control Valve

PURPOSE

Controls engine idle speed during closed loop operation.

OPERATION

It receives a pulse signal from the Engine Control Module which opens and closes an air passage allowing a precise amount of air to flow through
the valve. Longer pulses allow greater amounts of air to flow through the valve which increases idle speed.
