초록

The present invention is directed to an on-board diagnostic system for detecting a defective fuel line pressure regulator in an internal combustion engine during engine operation. Pressure sensor means are provided for sensing fuel pressure in the fuel supply line and for generating corresponding pressure signals. Signal processing means receive and process the pressure signals from the pressure sensor means. An output signal is generated by the signal processing means in the event pressure signals are determined to indicate a malfunctioning pressure reg...
