Code P1114 1999 Ford F150 Description

The P1114 diagnostic trouble code (DTC) for a 1999 Ford F150 indicates a problem with the Intake Air Temperature Sensor 2 Circuit being too low. The Intake Air Temperature (IAT) sensor is a crucial component of the engine management system, as it measures the temperature of the air entering the engine. This information is used by the engine control module (ECM) to adjust fuel delivery and ignition timing for optimal performance and efficiency.
