Abstract
A system and method for monitoring and controlling an engine based on an engine fluid pressure include sensing an engine fluid pressure, determining a current value for an engine operating parameter, determining whether the engine fluid pressure has crossed a first threshold corresponding to the current value of the engine operating parameter, determining whether the engine fluid pressure has crossed a second threshold corresponding to the current value of the engine operating parameter, generating a warning signal when the fluid pressure has crossed the first threshold but has not crossed the second threshold, and generating a shutdown signal when the fluid pressure has crossed the second threshold. In one embodiment, the second threshold is determined based on the first threshold by applying a constant offset value.
