Code P0113 2011 Ford Fusion Description

The Intake Air Temperature (IAT) sensor is built into Mass Air Flow (MAF) sensor. The sensor detects intake air temperature and transmits a signal to the Powertrain Control Module (PCM). The temperature sensing unit uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases in response to the temperature rise. The Intake Air Temperature signal is used as an input for various systems in the vehicle. It is used by the Powertrain Control Module to assist with the calculation of idle speed, fuel mixture, and spark advance. The Diagnostic Trouble Code (DTC) will set when the PCM detects an excessively high voltage from the sensor.
