Abstract

A method for activating an injector in a fuel injection system in an internal combustion engine, the fuel injection system including a plurality of injectors and a quantity of fuel injected with the aid of an injector being a function of the activation period of the injector. An injector-individual correction value for the activation period is ascertained for at least one injector as a function of a pressure and a temperature of the fuel to be injected and the activation for this injector takes place under consideration of the injector-individual correction value.
