P009A - INTAKE AIR TEMPERATURE/AMBIENT AIR TEMPERATURE CORRELATION

Description:  The DTC sets when the intake air temperature (IAT) and ambient air temperature (AAT) sensor readings differ by greater than a calibrated value.
Possible Causes: 
  • Biased IAT or AAT sensor
  • Damaged IAT or AAT sensor
Diagnostic Aids:  Make sure the IAT and AAT sensor readings are within 50°C (90°F) of each other while driving at a speed greater than 80.5 km/h (50 mph) with the ambient temperature less than 80°C (176°F) and the engine coolant temperature between -35°C (-31°F) and 121°C (250°F).
