Fuel Charging and Cotrols

Throttle Body

The electronic throttle body controls the engine torque and is located on the induction elbow at the rear of the engine. Its main components are an electronic throttle control valve, Accelerator Pedal Position (APP) sensor and the Engine Control Module (ECM).

The APP sensor determines the driver demand to control throttle opening. This value is received by the ECM and the throttle is then opened to the correct angle by means of an integral electric motor. Sensors in the throttle body are used to determine the position of the throttle plate and the rate of change in its angle.

Induction Elbow
The induction elbow provides the interface between the electronic throttle body and the supercharger. Connections on the induction elbow provide vacuum take off's for various vehicle systems.
