DTC is set when variation in intake air temperature is less than predetermined after engine is at operating condition. DTC is also set when intake air temperature is 21°F (-6C°) or less, or 140°F (60°C) or more. MIL is illuminated when Powertrain Control Module (PCM) detects malfunction during 2 consecutive drive cycles. Possible causes are:

• IAT sensor malfunction.
