GF30.20-P-2010MCU Accelerator Pedal Sensor, Component Description
1 Accelerator pedal module
B37 Accelerator pedal sensor
Location
The accelerator pedal sensor is located on the right on the accelerator pedal module.
Task
The accelerator pedal sensor converts the mechanical operation input by accelerator pedal into an electrical voltage corresponding to the accelerator pedal position.
Body
The accelerator pedal sensor consists of two Hall sensors and double detection electronics.
Function
This rotates in a printed circuit board with a stator in the two fixed Hall elements. This generates two different signal voltages, which inform the ME-SFI [ME] control unit (N3/10) about the current position of the accelerator pedal.
