Code P1125 Lincoln Description

The P1125 diagnostic trouble code (DTC) for Lincoln vehicles relates to an intermittent issue with the throttle position sensor (TPS). The throttle position sensor is a critical component of the electronic throttle control system, which helps regulate the amount of air entering the engine. The TPS is responsible for sending signals to the engine control module (ECM) to determine how much fuel should be injected into the engine based on the throttle position.
