Abstract
A control system is provided for use with an engine. The control system may have a coolant pressure sensor configured to generate a first signal indicative of a pressure of coolant circulating through the engine, and an oil pressure sensor configured to generate a second signal indicative of a pressure of oil circulating through the engine. The control system may also have a controller in communication with the coolant and oil pressure sensors. The controller may be configured to determine functionality of the coolant and oil pressure sensors during operation of the engine, and to selectively allow operation of the engine in a semi-protected mode when the coolant pressure sensor or the oil pressure sensor is determined to be non-functional.
