METHOD AND DEVICE FOR FAULT DETECTION DURING THE OPERATION OF A FUEL INJECTION SYSTEM

METHOD AND DEVICE FOR FAULT DETECTION DURING THE OPERATION OF A FUEL INJECTION SYSTEM

In a method for operating a fuel injection system for an internal combustion engine of a motor vehicle, an output signal of a pressure sensor which characterizes a fuel pressure in a pressure accumulator is evaluated. An undesirably high fuel pressure in the pressure accumulator and/or a fault in th...

description In a method for operating a fuel injection system for an internal combustion engine of a motor vehicle, an output signal of a pressure sensor which characterizes a fuel pressure in a pressure accumulator is evaluated. An undesirably high fuel pressure in the pressure accumulator and/or a fault in the fuel injection system is/are inferred at the time when the output signal assumes a maximally possible value for at least a predefinable monitoring period.
