P2106: Throttle Actuator Control System - Forced Limited Power
2 vehicles · 1 makes · $350-$900 repair
Most Reported On
P2106 is an OBD-II diagnostic trouble code meaning “Throttle Actuator Control System - Forced Limited Power.” P2106 means the engine computer has put the electronic throttle control (drive-by-wire) system into a 'forced limited power' or reduced-power mode. This code doesn't point to a failed part itself — it's a protective response, set because the computer detected another throttle-related fault (a bad throttle position sensor, accelerator pedal sensor, or throttle body) and limited engine power to keep you safe. You'll usually notice sluggish acceleration, a 'reduced power' warning, or the car feeling like it won't rev past a certain point. The underlying throttle fault, almost always stored as a companion code, must be found and fixed. This code is most commonly reported on 2005-2007 Ford Freestyle, and 2006-2010 Ford Explorer, with repair costs ranging from $350 to $900.
