These issues may be caused by an incorrect brake pedal position sensor input to the engine control module. Technician will verify with the scan tool if the engine control module has the correct parameters for the brake pedal position sensor. If an engine control module brake pedal position sensor relearn is performed, the truck may be temporarily repaired until the intermittent wiring issue between the engine control module and brake pedal position sensor occurs again. On 2014 and newer trucks inspect and repair any damage to X115 and X119. On the 2014 and previous trucks inspect and repair any damage to X205.
