Abstract (en)
[origin: WO2012007265A2] The invention relates to a method for operating a fuel injection system (130), in particular for an internal combustion engine (1) of a motor vehicle, in which an output signal (Sprail), which characterizes a fuel pressure (prail) in a pressure accumulator (13), of a pressure sensor (14) which is assigned to the pressure accumulator (13) is evaluated. According to the invention, an undesirably high fuel pressure is inferred in the pressure accumulator (13) and/or a fault is inferred in the fuel injection system (130) if the output signal (Sprail) assumes a maximum possible value (Smax) for at least one predefinable observation time period (Tb).
