P0127 - Intake Air Temperature Too 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 a reading from the sensor that indicates a temperature that is higher than expected when compared to other sensor values. The sensor output is likely to be within it’s normal operating parameters.

Recommended Tests

If possible use a diagnostic computer to view live data from the sensor and compare this to actual air temperature.
