Abstract

A circuit configuration for recording the resistance of a coil of a magnetic valve, having at least one magnetic valve, having at least one valve coil that is to be actuated, a current source for applying a current to the at least one valve coil and generating a voltage drop at the at least one valve coil, and an evaluation circuit for outputting the voltage drop generated at the at least one valve coil as the output signal of the circuit configuration.
