Code P1124 2012 Ford Fusion Description

The P1124 diagnostic trouble code (DTC) for a 2012 Ford Fusion indicates that the Throttle Position Sensor (TPS) is out of the self-test range. The TPS is a crucial component of the engine management 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 determine the appropriate air-fuel mixture for combustion, as well as to adjust the ignition timing and transmission shifting points.
