What Does P2111 Code Mean?

OBD-II Code P2111 is defined as a Throttle Actuator Control System - Stuck Open

The throttle motor is controlled by the engine computer (PCM). If the PCM does any movement from the throttle motor, code P2111 will set. The PCM may also put the engine into "limp home mode", limiting the available power from the engine to prevent unwanted acceleration.
