Abstract
A method for determining an error in a pressure, which is measured by means of a pressure sensor in a pressure accumulator for accumulating fuel that can be let out of the pressure accumulator via an injection valve and injected into a cylinder, wherein the method comprises: determining at least two 3-tuples of a first pressure, a period of time, and a second pressure, wherein each first pressure is measured by the pressure sensor; wherein after measuring each first pressure, the valve is opened for a period of time; and wherein after the opening of the valve for the period of time, the second pressure is measured by the pressure sensor; and determining the error of the measured pressure from the at least two 3-tuples.
