Abstract
A control system and method for detecting a hydraulic system leak in an engine includes a pressure sensor that senses a first pressure reading of a hydraulic fluid supply at a first time and a second pressure reading of said hydraulic fluid supply at a second time. A comparison module calculates a pressure ratio based on the first and second pressure readings and signals a fault condition based on a relationship between the pressure ratio and a pressure threshold.
