Abstract
A method is made available for monitoring a pressure sensor () in a pressure-controlled delivery and metering system for a liquid reactant of a catalytic converter, in particular of an SCR catalytic converter. The delivery and metering system is provided for delivering the reactant from a tank () and for metering the reactant via a pressure line () and a metering module (). In order to monitor the pressure sensor () which is located in the pressure line (), a flow rate measurement is carried out in the pressure line () and/or in a return path () taking into account the relationship between the pressure p and the corresponding flow rate v.
