Throttle Body Assembly
The Automatic Idle Speed (AIS) motor maintains idle speed under varying engine loads by controlling air flow into the intake manifold behind the
throttle plate through a bypass passage. The Single Board Engine Controller (SBEC) maintains optimum idle speed by actuating the AIS motor to open
or close the bypass opening according to a programmed response to inputs from various switches and sensors.
