Code P0098 Chevrolet Description

The P0098 Chevrolet diagnostic trouble code (DTC) indicates an issue with the Intake Air Temperature Sensor 2 Circuit being too high. This sensor is responsible for measuring the temperature of the air entering the engine, which is crucial for the proper functioning of the engine control unit (ECU) to adjust the air-fuel mixture for optimal combustion. When the sensor detects a high voltage signal, it means that the intake air temperature is higher than expected, which can lead to various performance issues.
