Code P1124 Lincoln Description

The P1124 diagnostic trouble code (DTC) for Lincoln vehicles 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 unit (ECU). The ECU uses this data to adjust fuel delivery and ignition timing to optimize engine performance.
