Abstract
Verfahren zur Überprüfung eines Drucksensors (S) einer Kraftstoffeinspritzeinrichtung, insbesondere eines Kraftfahrzeugs, wobei die Kraftstoffeinspritzeinrichtung einen Druckspeicher (9) aufweist, dem der Drucksensor (S) und ein Einspritzventil (11) zugeordnet ist, wobei bei dem Verfahren eine Kraftstoffmenge (Q) unter einem Druck (pl) von dem Einspritzventil (11) eingespritzt wird, dadurch gekennzeichnet, dass eine Druckdifferenz (Δp1), die durch einen Druckeinbruch auf Grund des Einspritzvorgangs entsteht, in Abhängigkeit von dem Druck (pl) und der Kraftstoffmenge (Q) ermittelt wird. A method for checking a pressure sensor (S) of a fuel injection device, in particular of a motor vehicle, wherein the fuel injection device has a pressure accumulator (9) to which the pressure sensor (S) and an injection valve (11) is assigned, wherein in the method a fuel quantity (Q) below a pressure (pl) from the injection valve (11) is injected, characterized in that a pressure difference (Δp1), which results from a pressure drop due to the injection process, in dependence on the pressure (pl) and the amount of fuel (Q) is determined ,
