Camry Sedan 4-Door L4-132 2164cc 2.2L DOHC (5S-FE) (1995)
Idle Speed/Throttle Actuator - Electronic: Description and Operation
PURPOSE
The Idle Air Control (IAC) Valve is used to maintain proper idle speeds during varying conditions.
OPERATION
The IAC valve receives a continuous signal from the ECM. Using the signal the ECM is able to control the size of the air passage through the
valve. Air passing through the valve bypasses the throttle plate which causes an increase in idle speed.
