Throttle Body:

The throttle body assembly is mounted on the intake manifold and houses the throttle plate, fuel injector, fuel pressure regulator, temperature and position sensors, and the AIS motor. Intake air flow is controlled by the cable operated throttle plate and by a separate by-pass channel which is controlled by the AIS motor. The throttle body provides the chamber for fuel metering, atomization, and mixing atomized fuel with incoming air.
