Code P2199 2016 GMC Sierra Description

The P2199 diagnostic trouble code (DTC) for a 2016 GMC Sierra indicates that the Intake Air Temperature Sensor 1-2 is not plausible. This means that the Engine Control Module (ECM) has detected a discrepancy between the intake air temperature readings from Sensor 1 and Sensor 2, which are located in the intake air duct. The ECM uses these sensors to monitor the temperature of the incoming air to adjust the air-fuel mixture for optimal combustion in the engine. When the readings from the two sensors do not align, it can lead to performance issues and potentially cause damage to the engine.
