July 1: So it begins. Don't worry, this is not in the correct legal jurisdiction!

Diagnostic Aids

After confirming DTC P0110, use scan tool to access CURRENT DATA to confirm intake air temperature. If IAT sensor value displayed on scan tool is always -40°F (-40°C), IAT sensor circuit may be open. If IAT sensor value displayed on scan tool is always 284°F (140°C), IAT sensor circuit may be shorted. Using scan tool, read freeze frame data. Freeze frame records engine conditions when malfunction is detected.
