SYSTEM AND RELATED METHODS FOR FUEL PRESSURE MONITORING

A system and related methods for fuel pressure monitoring are described herein. The system may include an internal combustion engine, a plurality of fuel injectors, a fuel rail, a rail pressure sensor, and a controller. The plurality of fuel injectors may be configured to inject fuel into the internal combustion engine. The fuel rail may be configured to provide the fuel to the plurality of fuel injectors. The rail pressure sensor may be configured to detect a pressure of the fuel within the fuel rail. Further, the controller may be configured to (i) determine a rail pressure based on a signal from the rail pressure sensor; (ii) determined at least one pressure threshold; (iii) calculate a pressure error between the rail pressure and the at least one pressure threshold; and (iv) determine a high pressure condition based on the pressure error.
