Code P2104 2003 Ford F150 Description

The P2104 diagnostic trouble code (DTC) for a 2003 Ford F150 relates to the Throttle Actuator Control System Forced Idle. This code indicates that there is a malfunction in the electronic throttle control system, specifically that the throttle actuator control system is being forced into an idle position. The electronic throttle control system, also known as drive-by-wire, eliminates the need for a mechanical link between the accelerator pedal and the throttle body. Instead, sensors and electronic control units (ECUs) communicate to control the throttle opening.
