Throttle body is a part of the engine's air intake system, as long as your car has fuel injection. It is located before the engine's intake manifold and regulates the flow of air to the engine and air mixes with fuel to help under go combustion. It consists of a butterfly valve that opens and closes depending on how much air is required to the engine and this opening and closing depends on the input given by the driver when the throttle paddle is pushed down to the floor.

The throttle body is mounted between the air filter and the intake manifold. Throttle body designs vary. Some are equipped with an idle air control valve, throttle position sensor, and other electronic throttle controls. The throttle plate on the throttle body can be controlled directly via an accelerator pedal cable or fully electronically on newer cable drive systems.
