Code P0098 2016 GMC Sierra Description

The P0098 diagnostic trouble code (DTC) for a 2016 GMC Sierra relates to the Intake Air Temperature Sensor 2 Circuit High. This code indicates that the Engine Control Module (ECM) has detected a high voltage signal from the intake air temperature sensor 2. The intake air temperature sensor is responsible for measuring the temperature of the air entering the engine. This information is crucial for the ECM to adjust the air-fuel mixture and ignition timing to optimize engine performance and fuel efficiency.
