How does a throttle body work? What is a throttle body? A throttle body is a butterfly valve located between the air intake filter and the intake manifold. It regulates how much air can go into the engine, based on driver input through the gas pedal. As more air flows into the engine, it injects more fuel, thus allowing for more power. Throttle bodies today are mostly electronically controlled, where this throttle body is mechanical. It includes input for TPS and MAP sensors, as well as routing for the IAC valve, and a idle adjustment screw.
