Was driving along today and had the dead pedal happen to my Cummins, engine never quit, stayed idling pulled over and it seemed fine so took off driving, never acted up again today, got home and hooked up to scanner and it shows a code PO 121 throttle/pedel position sensorA circuit performance, anybody have this problem or know fix for it. Thanks, Terry
