Code P2105 Ford Description

The P2105 Ford trouble code indicates an issue with the Throttle Actuator Control System, specifically a forced engine shutdown. This code is typically triggered when the Engine Control Module (ECM) detects a problem with the electronic throttle control system, leading to the system shutting down the engine to prevent any potential damage or safety hazards. The throttle actuator control system is responsible for managing the opening and closing of the throttle valve to regulate the airflow into the engine, ultimately controlling the engine speed and power output.
