P0098 - Intake Air Temperature Sensor 2 - Circuit High

System Information

Intake Air Temperature is monitored to allow the ECM to accurately adjust fueling and emission control systems as the temperature directly affects the air density

Fault Code Explained

The ECM has detected that the sensor output is above it’s maximum operating parameter or is higher than expected for the current operating conditions.

Recommended Tests

If possible use a diagnostic computer to view live data readings for the sensor and compare to actual air temperature. Test sensor supply Voltage and output signal, it is possible that the output signal is shorted to positive.
