Abstract
A method for operating a pressure-regulating valve of a fuel injection system of an internal combustion engine of, in particular, a motor vehicle; the fuel injection system including a pressure reservoir for storing pressurized fuel, as well as a feed device for delivering fuel to the pressure reservoir; and fuel being removable from the pressure reservoir via the pressure-regulating valve. In an overrun mode of the internal combustion engine, a delivery quantity of fuel delivered to the pressure reservoir by the feed device is set to a value greater than zero, and that a fuel pressure in the pressure reservoir is ascertained.
