What Does the P0113 Infiniti Code Mean?

The Intake Air Temperature (IAT) sensor is built into the Mass Air Flow (MAF) sensor or in some vehicles mounted to the air filter duct housing. The sensor detects intake air temperature and transmits a signal to the Engine Control Module (ECM). 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. The Diagnostic Trouble Code (DTC) will be set when an excessively high voltage from the sensor is sent to ECM.
