Code P0111 2015 Ford F150 Description

The Intake Air Temperature (IAT) Sensor is a thermistor device in which resistance changes with temperature. The resistance of a thermistor decreases as the temperature increases, and the resistance increases as the temperature decreases. The varying resistance affects the voltage drop across the sensor pins and provides electrical signals to the Powertrain Control Module (PCM) corresponding to temperature.
Thermistor-type sensors are considered passive sensors. A passive sensor is connected to a voltage divider network so that varying the resistance of the passive sensor causes a variation in total current flow. The voltage that is dropped across a fixed resistor in a series with the sensor resistor determines the voltage signal at the PCM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor.
The IAT sensor provides air temperature information to the PCM. The PCM uses the air temperature information as a correction factor in the calculation of fuel, spark, and airflow.
The IAT sensor provides a quicker temperature change response time than the Engine Coolant Temperature (ECT) or Cylinder Head Temperature (CHT) sensor.
Currently, there are 2 types of IAT sensors used, a stand-alone and an integrated type. Both types function the same, however, the integrated type is incorporated into the Mass Air Flow (MAF) Sensor, the Manifold Absolute Pressure and Temperature (MAPT) Sensor, or the Turbocharger Intake Pressure and Temperature (TCIPT) Sensor instead of being a stand-alone sensor.
This Diagnostic Trouble Code (DTC) will be set if the IAT Sensor value exceeds the maximum calibrated temperature threshold while driving.
