<P> Electronic throttle control ( ETC ) is an automobile technology which electronically `` connects '' the accelerator pedal to the throttle , replacing a mechanical linkage . A typical ETC system consists of three major components : ( i ) an accelerator pedal module ( ideally with two or more independent sensors ) , ( ii ) a throttle valve that can be opened and closed by an electric motor ( sometimes referred to as an electric or electronic throttle body ( ETB ) ) , and ( iii ) a powertrain or engine control module ( PCM or ECM ) . The ECM is a type of electronic control unit ( ECU ) , which is an embedded system that employs software to determine the required throttle position by calculations from data measured by other sensors , including the accelerator pedal position sensors , engine speed sensor , vehicle speed sensor , and cruise control switches . The electric motor is then used to open the throttle valve to the desired angle via a closed - loop control algorithm within the ECM . </P>
