APP sensors mounted on the accelerator pedal assembly (accelerator pedal position sensor).
APP sensors (accelerator pedal position sensor) provide control of the driver's commands to accelerate, decelerate or maintain vehicle speed. Sensor signal used by ECM (the engine control unit) in order to use the electric motor built into the throttle body to set the throttle valve to the desired position.
APP sensor signals (accelerator pedal position sensor) tested for absolute value and validity. The pedal is supplied with two different reference voltages. If one sensor fails, the signal of the second one will be used in the emergency control mode. If the emergency control mode is caused by an incorrect APP signal (accelerator pedal position sensor) , ECM (the engine control unit) limits the maximum engine speed to 2000 rpm.
