Idle Air Control Valve Unit: Description and Operation
The Idle Air Control Valve unit is made up of the IACV-AAC valve, IACV-FICD solenoid valve and idle adjusting screw. It receives the signal from the
ECM and controls the idle speed at the preset value. The IACV-FICD solenoid valve compensates for changes in idle speed caused by the operation of
the air compressor.
