摘要： A diagnostic system includes a fuel pump module and a diagnostic control module. The fuel pump module activates a first pump when an engine is operating in a diagnostic mode. The first pump supplies fuel to fuel injectors of the engine via a fuel rail. The diagnostic control module receives a measured pressure signal from a pressure sensor that indicates a pressure of the fuel rail during the diagnostic mode. The fuel pump module sends at least one of a first and a second commanded fuel pressure signal to the first pump based on a predetermined relief pressure of a pressure relief valve. The diagnostic control module detects a fault of the pressure sensor based on an engine speed and a comparison between the measured pressure signal and at least one of the first commanded fuel pressure signal and a corrected relief pressure of the pressure relief valve.
