Code P0114 GMC Description

The P0114 GMC diagnostic trouble code indicates that there is an intermittent issue with the Intake Air Temperature (IAT) sensor circuit. The IAT sensor is responsible for measuring the temperature of the air entering the engine. This information is crucial for the vehicle's Engine Control Module (ECM) to adjust the air-fuel mixture for optimal combustion.
