ABSTRACT:
The invention is directed to a method of checking a pressure sensor of a fuel supply system of an internal combustion engine such as an engine for a motor vehicle. The fuel supply system includes a pressure store to which fuel is supplied and a pressure sensor for measuring the pressure in the pressure store. Fuel is supplied from the pressure store to a combustion in the engine and the pressure in the pressure store is changed. The behavior of the combustion of the fuel is detected and a conclusion is drawn as to the operability of the pressure sensor from the detected behavior of the combustion.
