Summary:A method for controlling a pressure control valve which controls the pressure in a high-pressure accumulator of a fuel metering system of an internal combustion engine, fuel being metered into the combustion chambers of the internal combustion engine from the high-pressure accumulator, and the pressure control valve being connected to the high-pressure accumulator and controlling the outflow of fuel from the high-pressure accumulator into a low-pressure accumulator, and it being provided, in particular, that in the case of a closed pressure control valve, the energization of the pressure control valve is reduced until the pressure control valve opens, and a close offset input is ascertained based on the energization present at the opening of the pressure control valve.
