This component is known as the external accelerator pedal assembly or electronic throttle pedal , or pedal position sensor . It's an integrated unit that mounts to the floor of JAC GS3 and GA4 vehicles. It operates using a drive-by-wire system. Its primary function is to convert the driver's pedal pressure into an electrical signal, which is then sent to the engine control unit (ECU). The ECU uses this signal to determine the amount of fuel and air required to change engine speed. This TAC PART component is designed to be a replacement for the original factory part, maintaining the accuracy of the electronic signals and the pedal's responsiveness.
If the car experiences a delay or hesitation when pressing the accelerator pedal, or does not respond to pressure at all, or the check engine light comes on with fault codes indicating a problem with the pedal position sensor, this indicates that the unit is damaged and needs to be replaced.
⚠️ Important Notice: Please make sure the part matches your vehicle's chassis number before purchasing the product or after ordering.
