P0096 - Intake Air Temperature Sensor 2 Circuit Range/Performance
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 sensor output signal is likely to be within it’s normal operating parameters but is not as expected for the current operating conditions. The ECM may have detected the sensor output is incorrect when compared with other sensor values.
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
