Throttle Body Assembly

Throttle Body Assembly:

The throttle body assembly attaches to the intake manifold. The throttle body controls air flow into the engine, thereby controlling engine output. The throttle actuator motor mounted on the throttle body opens the throttle valve within the throttle body. Engine coolant flows through the coolant cavity on the bottom of the throttle body in order to prevent throttle valve icing during cold weather operation. The throttle body also provides the location for mounting the Throttle Position (TP) sensor.
