Code P1114 2010 Ford Fusion Description

The P1114 diagnostic trouble code (DTC) for a 2010 Ford Fusion indicates a problem with the Intake Air Temperature Sensor 2 Circuit being too low. This sensor is responsible for measuring the temperature of the air entering the engine, which is crucial for the engine control unit (ECU) to adjust the air-fuel mixture for optimal combustion. When the intake air temperature sensor 2 circuit is reading lower than expected, it can lead to incorrect fuel delivery, affecting the engine's performance and efficiency.
