What does the accelerator pedal position sensor do?

The accelerator pedal sensor of Pacific Auto Network is usually called the accelerator position sensor. Its function is to transmit these signals to the ECU electronic control unit of the automobile through the circuit, and then the ECU electronic control unit of the automobile carries out comprehensive processing by adding various sensor signals to this transmitted signal, and finally controls the work of each actuator.

Electronic accelerator pedal position sensor is an important part of electronic accelerator system. The electronic accelerator transmits the signals of the depth and speed of the accelerator pedal through the electronic accelerator pedal position sensor, and the ECU will receive and interpret these signals, and then send out control instructions, requiring the accelerator to open the angle it should open quickly or gently according to the instructions. The electronic accelerator system is mainly composed of accelerator pedal, electronic accelerator pedal position, ECU data bus, servo motor and accelerator actuator.

The electronic accelerator pedal position sensor is installed in the accelerator pedal to monitor the position of the accelerator pedal at any time. When it detects that the height position of the accelerator pedal changes, it will immediately send this information to the ECU, which will calculate and process this information and data information from other systems to calculate a control signal and send it to the servo motor relay through the line. The servo motor drives the throttle actuator, and the data bus is responsible for the communication between the system ECU and other ECU. (Photo/Text/Photo: Pacific Auto Network)
