ABSTRACT:
A method is for making a diagnosis as to signal plausibility in a speed sensor of a motor vehicle. In the method, the speed sensor outputs a pulse sequence to an evaluation circuit in dependence upon the speed of the vehicle and, in a steady-state operating condition of the motor vehicle, a ratio is formed between the determined speed and an engine rpm and the ratio is averaged over a pregiven time. A plausibility is determined only when the formed mean value lies in a value range permissible for the steady-state operating condition.
