P0073 Ambient Air Temperature Circuit High - General Information

Component Location





General Description

A value from modeling that have been retrieved from an intake air temperature sensor has been currently been in use for outside temperature detection. However, it is difficult to use this value due to the properties of the turbo charger, because the temperature shows a great increase during the charging. Therefore, the outside temperature sensor is installed in front of the radiator to directly measure the outside temperature.

DTC Description

ECM sets DTC P0073 if the ECM detects ambient air temperature signal circuit is short to battery or open.
