Abstract
A method for predefining a current through a solenoid coil of a solenoid valve, a closing point in time of the solenoid valve being detected with the aid of a sensor, a sensor value being monitored, and, when a premature closing of the solenoid valve is identified based on the monitored sensor value, the current through the solenoid coil of the solenoid valve is increased.
