Code P0114 2016 GMC Sierra Description

The intake air temperature (IAT) sensor 1 is a variable resistor that measures the temperature of the air in the sensor bore. The Engine Control Module (ECM) supplies 5 V to the IAT sensor 1 signal circuit and a ground for the IAT sensor 1 low reference circuit. The signal varies with inlet air temperature and is displayed by the scan tool as °C (°F). The multifunction intake air sensor houses the IAT sensor 1, IAT sensor 2, Humidity sensor, Mass Air Flow (MAF) sensor and BARO pressure sensor. The Diagnostic Trouble Code (DTC) ECM detects that the IAT sensor 1 signal is intermittent or has abruptly changed for greater than 5 s.
