P2111: Throttle Actuator Control System - Stuck Open
10 vehicles · 4 makes · $100-$900 repair
Most Reported On
P2111 is an OBD-II diagnostic trouble code meaning “Throttle Actuator Control System - Stuck Open.” This code sets when the throttle actuator control (electronic throttle) system detects that the throttle plate is stuck in an open position and is not closing as commanded. Modern engines use a 'drive-by-wire' throttle where a motor moves the throttle plate based on accelerator pedal input, and dual position sensors confirm its actual angle. When the computer commands the throttle to close but the sensors show it remaining open, it sets this code and typically forces the engine into a reduced-power 'limp' mode for safety. It generally points to a mechanical bind, a failing throttle motor, or sensor issues inside the throttle body. 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 $100 to $900.
