GM
Type:
    Powertrain - Manufacturer Controlled DTC - Manufacturer Controlled
Description:
    IAT Sensor Circuit Intermittent High Input Conditions
Cause:
    No ECT, MAF or VSS codes set, engine runtime 5 seconds, ECT input more than 140°F, MAF input less than 12 g/sec, VSS input under 48 mph, then the PCM detected an intermittent IAT sensor input that was more than 4.8v (-12°F), conditions met for 1 second
