Peugeot 206 electronic throttle

206 electronic throttle opening feedback signal is a differential signal. The greater the opening, the greater the voltage difference between the two lines, and vice versa. The accelerator pedal signal is converted into an opening signal of 0-5V by ECU. The deeper the accelerator, the higher the voltage. The signal is input to the servo driver in the electronic throttle, and the driver automatically controls the position of the throttle according to the signal. Then, the actual position of the throttle valve is converted into the above differential signal by the internal position sensor and fed back to the ECU. The feedback opening signal is also one of the key parameters to control the fuel injection quantity.
