Abstract
The invention is directed to an arrangement for detecting a changing operating parameter of an internal combustion engine and/or of a motor vehicle especially for measuring angle. The arrangement has at least two measuring devices detecting the particular operating parameter and these measuring devices have pregiven characteristics for generating signal values representing the operating parameter. The characteristics have respectively different forms and are linear over the value range of the operating parameter and the characteristic of at least one of the measuring devices has a slope which deviates from that of the other measuring device. Irregularities in the area of the common voltage supply of the measuring devices can be detected by correlating the signal values generated by the measuring devices having characteristics deviating from each other.
