The disclosure relates to an apparatus and a method for driving a solenoid valve. The apparatus comprises a PWM apparatus, an evaluation and control unit, and a current measuring apparatus The evaluation and control unit is configured to: in a test operation, generate and emit test PWM signals having test duty ratios, the test PWM signals inducing test currents through a magnet assembly of the solenoid valve that are below a response threshold that triggers a switching process of the solenoid valve; derive presently prevailing ambient conditions of the test operation from the test PWM signals and the induced test currents; and in a normal operation generate and emit a PWM signal based on the presently prevailing ambient conditions of the test operation, the PWM signal inducing a current that is above the response threshold and switches the solenoid valve.
