While driving my F350 the check engine light comes on when I brake, the truck will not respond when I press down on foot pedal. The engine continues to run but will not rev up, It acts as if the foot pedal is not connected. It only last a second, Once I press down on the foot pedal & release the Check Engine Light goes off on the Truck operates fine. I have had it in the shop to replaced all injectors and replace a leaking fuel drain valve, but the problem still exists.
Are you a 7.3. A cam sensor will do this, but it codes up injectors, When a check engine light comes on its either a rational or a logic code. And PID data is not much help, Suspect the cam sensor, why it runs but will not rev up. That is cam sensor, truck operates fine, thats the cam sensor.
