Abstract
An arrangement for detecting a changing variable in a motor vehicle includes at least one transducer having terminals with at least one terminal being connected to a pole of a supply voltage. In addition, an actuable switch element is provided which interrupts at least one connecting line connected to a terminal. The potential of this terminal is detected relative to a reference potential when the switch element is open and a fault state of the transducer is assumed when there is an impermissible fluctuation of the potential value during at least two detecting operations.
