Code P011C Nissan Description

The Intake Air Temperature (IAT) sensor is built-into mass air flow sensor. 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. Electrical resistance of the thermistor decreases in response to the temperature rise.
