coolant temperature.
The opening angle of the throttle valve will only be determined by the accelerator pedal signal when no limiting functions are active.
The accelerator pedal position sensor is detected by the nominal value potentiometer or hall sensor in the pedal value sensor and information is released
to the PCM. The PCM determines the position of the throttle valve and actuates the throttle valve motor.
The actual value potentiometer in the actuator signals the throttle valve position back to the PCM.
The second potentiometer in the actuator and the second signal from the pedal value sensor (potentiometer or hall sensor) supplies a reference value for
the plausibility check. The system switches over to the second potentiometer or the hall sensor if the first potentiometer or hall sensor fails (emergency
mode).
The accelerator pedal position sensor on the accelerator pedal works according to the hall principal. the sensor is integrated into the pedal lever axis. It
consists of a shaft with a ring magnet. This rotates in a printed circuit board with a stator in the fixed hall elements. This produces a change in the
voltage.
The accelerator pedal position sensor is supplied with 5 volts from the PCM. The information regarding accelerator position is supplied to the PCM by
means of two voltages (pin 4: approximately 0 up to 2.25 volts and pin 5: approximately 0 up to 4.5 volts).
The kickdown simulator is not used as a "kickdown switch". Wide Open Throttle (WOT) recognition takes place over the signal from the accelerator
pedal position sensors pressure point, which is located in the pedal assembly. WOT position is simulated before achieving the full load position.
