A system and method of diagnosing a clutch pedal position sensor of a vehicle includes determining if a speed of the vehicle speed is less than a first predetermined speed, recording a maximum clutch pedal voltage, determining if a vehicle launch event is in progress, recording a minimum clutch pedal voltage, determining a voltage difference between the maximum clutch pedal voltage and the minimum clutch pedal voltage, and declaring a clutch pedal position sensor fault based on a comparison between the voltage difference and a threshold voltage.
