Code P1124 2007 Ford Fusion Description

The P1124 code for a 2007 Ford Fusion indicates that the Throttle Position Sensor (TPS) is out of the self-test range. The TPS is a crucial component of the vehicle's electronic fuel injection system, as it monitors the position of the throttle valve and sends this information to the engine control module (ECM). This data is used by the ECM to calculate the correct air-fuel mixture for optimal engine performance.
