I believe the pedal sensor has two totally redundant position sensors. If one fails or if they disagree, the car will go into limp mode and turn on the MIL. Maybe not all of them are like that, but I remember AvE (the YouTube channel) having to replace the pedal sensor on one of his cars a number of years ago and he talked about how they worked.
