The Engine Control Module (ECM) detects the following conditions:
•The intake manifold air temperature is equal to 90 °C (194 °F) or above 90 °C (194 °F).
•The engine coolant temperature is greater than 99 °C (210.2 °F).
•The engine has been running for at least 30 seconds.
Note: This diagnostic code represents a critical event. This diagnostic code does not represent an electronic system fault.
Possible Causes:
1) Sensor failure
2) Sensor connector/harness
3) Check connection at ECM and harness between sensor & ECM
