Throttle Body: Description and Operation
Throttle Body
The throttle body assembly is located between the turbocharger and the intake manifold and houses the throttle plate, throttle position sensor, and the
Automatic Idle Speed (AIS) motor. Intake air flow is controlled by the cable operated throttle plate and a separate idle air by-pass channel (controlled
by the AIS motor). Engine idle speed is controlled by the AIS motor adjusting the amount of air passing through the air by-pass channel. At idle the
throttle plate is closed.
