The throttle body is like the throttle on a car. It is mounted on the pipe between the air flow meter and engine. The throttle body can be controlled by your accelerator pedal, that moves it to open or close the throttle valve (hole). That’s what makes it work like a carburetor too. The electronic throttle body helps make sure there is enough air coming in for good fuel mixing inside of your engine.
