Accelerator pedal sensor
A new sensor which incorporates two potentiometers (no
idling switch is provided) is available on the accelerator
pedal. The ratio between the signals from the two
potentiometers is 2:1 (one potentiometer exhibits a twofold
resistance value compared with the other). Both of these
signals (V) are detected by the control unit that processes
them according to stored threshold values and manages the
injection system as an accelerator pedal position set by the
driver. (At the output of these potentiometers, a variable
voltage is available which corresponds to the potentiometer
resistance value.)
It is connected to the EDC control unit connector K pins
9-30-45-31-8-46. The potentiometers are powered with
5 V voltage supplied by the control unit itself.
