Conditions for Setting the DTC: P0113
WARNING: This page is about a different variant/trim than selected.
The ECM detects that the intake air temperature is less than -42°C (-44°F) and remains steady within 3°C (5°F) during an air flow increase of greater than 999 grams. The scan tool is limited to -40°C (-40°F), so the diagnostic procedure uses -39°C (-38°F) to determine if there is an IAT condition. The condition exists for greater than 4 seconds or cumulative of 50 seconds.
