General Information
WARNING: This page is about a different car, the 2017 Kia Soul EV. However, it is still accessible from the selected car via links, so may be relevant.
The accelerator pedal position sensor (APS) is the sensor which detects the amount the accelerator pedal is pressed to judge the intention of driver to accelerate, and sensors 1 and 2 are installed on top of the pedal. The voltage value of sensors 1 and 2 increases as the pedal is pressed, and sensor 2 displays half of value displayed by sensor 1. EPCU recognizes APS1 signal as the position value of accelerator pedal and controls the drive motor.
