Engine Coolant Temperature Sensor Monitoring
Range Check
The engine coolant temperature is electrical O.K., if the following condition is true:
Diagnosis threshold min. < engine coolant temperature < Diagnosis threshold max.
Plausibility Check low-side
The engine coolant temperature is plausible, if:
(reference temperature - threshold) < engine coolant temperate
Plausibility Check high-side
The engine coolant temperature is plausible, if:
(engine coolant temperature - reference temperature) > threshold
