Method for detecting a fault of a fuel pressure sensor for a high-pressure pump of a (GDI) engine

摘要

A method for detecting a failure of a fuel pressure sensor for a high pressure pump of a GDI engine includes a data collecting step of collecting information about a state of a vehicle. A sensor condition determination step determines whether data collected in the data collection step satisfies conditions for detecting a failure of the fuel pressure sensor. An error determination step determines whether the fuel pressure value of the pressure sensor for the high pressure pump is greater than or equal to a first reference value and simultaneously whether a fuel amount learned value is greater than or equal to a second reference value.
