B. Accelerator Sensor The accelerator sensor is a non-contact type. It is linked to the movement of the accelerator pedal, which rotates the lever, and the voltage of the output terminal changes according to the rotational position of the lever. There are hole el- ements on the sensor. A magnet is installed on the shaft, which moves together with the accelerator pedal, so the mag- netic field changes with the rotation of the shaft. A voltage is generated from these changes in the magnetic field.
