ABSTRACT:
A device and a method of monitoring a fuel metering system of an internal combustion engine, in particular a common rail system. The fuel is compressed by a pump, and a pressure variable characterizing the fuel pressure is determined. An error is detected when a filtered pressure variable deviates from a threshold value.
