Zusammenfassung:	A method for testing and/or correcting a fuel pressure sensor provided for detecting a fuel pressure in a combustion controlled internal combustion engine of a motor vehicle is disclosed. In at least one test run, the fuel pressure is changed from a working pressure value to a test pressure value when the combustion control is active. After the change of the fuel pressure a desired fuel injection duration and an actual fuel injection duration are compared with one another. An internal combustion engine device for carrying out the method is also disclosed.
