Abstract

The invention is directed to a method and an arrangement for checking the operability of the measured value detection system for an electronic power control arrangement of a motor vehicle. In the invention, and to check operation, the measured variable is converted by an analog/digital converter of the computer and is compared to a signal level determined from a signal derived from this measured variable. A fault condition in the area of the measured value detection system is assumed when impermissible deviations are determined between the two signals.
