Code P2101 2002 Ford F150 Description

The P2101 diagnostic trouble code (DTC) for a 2002 Ford F150 indicates a problem with the Throttle Actuator Control (TAC) system's motor circuit. This code specifically refers to a range/performance issue, which means that the powertrain control module (PCM) has detected that the position of the throttle actuator control motor is outside the expected range or is not performing within the predetermined parameters. The throttle actuator control motor is responsible for controlling the opening and closing of the throttle valve, which regulates the amount of air entering the engine.
