P2112: Throttle Actuator Control System - Stuck Closed

Most Reported On
P2112 is an OBD-II diagnostic trouble code meaning “Throttle Actuator Control System - Stuck Closed.” P2112 means the throttle actuator control (electronic throttle) system is stuck in the closed position. On drive-by-wire engines the computer moves the throttle plate with an electric motor and confirms its position with sensors; when it commands the throttle open but the plate won't move past closed, this code sets. This usually triggers limp/failsafe mode with greatly reduced power, a poor or surging idle, or a no-acceleration condition. It points to a mechanical or electrical problem in the throttle body or its control circuit. This code is most commonly reported on 2005-2007 Ford Freestyle, 2014-2021 Ford Transit Connect, and 2015-2019 Ford Transit, plus 7 other vehicles, with repair costs ranging from $30 to $900.
