Going down a bumpy-gravel road, I suddenly lost all throttle response in my 2016 Ford F150 with a 3.5 Ecoboost. I also got messages displaying "See Manual", "Service AdvanceTrac", and "Hill Start Assist Not Available". After coasting to a stop, I plugged in my code reader to find a P2112, Throttle Actuator Control System - Stuck Closed.
Modern drive-by-wire electronic throttle control systems will often exhibit an unresponsive throttle or rough idle condition if a fault is detected in the throttle control circuit. Trouble codes P2107, P2108, P2111, P2112, P2118 and P2119 are all throttle circuit related codes.
