Zusammenfassung:	A control system for evaluating an engine oil temperature sensor is provided. The control system includes a first diagnostic module that selectively detects a first engine oil temperature sensor fault based on a comparison of engine coolant temperature, intake air temperature, and engine oil temperature. A reporting module selectively generates a fault report based on the first engine oil temperature sensor fault.
