Working principle of five-wire throttle motor

The working principle of the five-wire electronic throttle is that the throttle opening is controlled by the motor, and the throttle line between the throttle pedal and the throttle is cancelled. In other words, the driver's acceleration intention will be transmitted to the engine controller through the position sensor of the accelerator pedal, and the engine controller will adjust the throttle body through the motor. At the same time, the electronic throttle opening sensor feeds back the detected opening signal to ECU to realize the closed-loop control of electronic throttle opening.
