Code P0114 2016 GMC Sierra Description

The P0114 diagnostic trouble code (DTC) for a 2016 GMC Sierra indicates an issue with the Intake Air Temperature (IAT) Circuit being intermittent. The IAT sensor is responsible for measuring the temperature of the air entering the engine. This information is crucial for the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. An intermittent circuit problem means that there is a sporadic interruption in the signal between the IAT sensor and the ECM.
