The electronic throttle body function can affect a Ford F150's performance and cause it to go into limp mode. When the throttle body fails, it can cause the truck to enter limp mode with reduced power[1][2][3]. This happens because the engine control unit (ECU) restricts or alters the engine's maximum speed, ignition timing, and other parameters[4]. The truck may also display error codes such as P2110 and P2107 for throttle body actuator/sensor[3]. Limp mode is a safety feature that limits the vehicle to one gear and/or 30-45 mph to prevent further damage[5].
