The throttle is usually a butterfly valve assembly on the intake manifold, and is connected to the accelerator, or gas pedal, via the throttle linkage. This linkage enables you to control the engineâs throttle by how far you move the gas pedal â the further down you press the gas pedal, the more the throttle opens.
