Abstract
A system includes a pedal position sensor that senses a pedal position of a vehicle pedal when the vehicle pedal is in a known position. The system also includes a learn window determination module that selects between a first pedal position range and a second pedal position range that corresponds to the known position. The system further includes a pedal fault determination module that determines a fault in the vehicle pedal based on the pedal position and the selected one of the first pedal position range and the second pedal position range.

A system comprising:
- a pedal position sensor that senses a pedal position of a vehicle pedal when the vehicle pedal is in a known position;
- an engine control module that selects between a first pedal position range and a second pedal position range based on a location of the engine control module and that determines a fault in the vehicle pedal based on the pedal position and the selected one of the first pedal position range and the second pedal position range.
A method comprising:
- using an electronic circuit:
- sensing a pedal position of a vehicle pedal when the vehicle pedal is in a known position;
- selecting between a first pedal position range and a second pedal position range based on a location of the vehicle pedal;
- and
- determining a fault in the vehicle pedal based on the pedal position and the selected one of the first pedal position range and the second pedal position range.
