Code P1124 Mercury Description
The P1124 diagnostic trouble code (DTC) for Mercury vehicles indicates that the throttle position sensor is out of self-test range. The throttle position sensor (TPS) is a crucial component that monitors the position of the throttle valve in the engine. It sends signals to the engine control unit (ECU) to adjust fuel injection, ignition timing, and other parameters to optimize engine performance. When the TPS is out of self-test range, it means that the ECU is not receiving the expected signal from the sensor, which can lead to various performance issues.
