Code P0111 2006 Ford Fusion Description

The P0111 code for a 2006 Ford Fusion indicates a problem with the Intake Air Temperature (IAT) Sensor 1 Circuit, specifically relating to range/performance issues. The IAT sensor is responsible for measuring the temperature of the air entering the engine, which is crucial for the engine control module (ECM) to adjust fuel delivery and ignition timing accordingly. When the ECM detects that the IAT sensor's signal is outside of the expected range or performance parameters, it triggers the P0111 trouble code.
