A ratiometric signal correction system, especially for angular position of a butterfly valve in an internal combustion engine in a motor vehicle which is input from one sensor to several control units is disclosed. A first control unit serves as reference, and mark pulse signals are transmitted to the or each further control unit when the butterfly valve is in either of two predetermined angular positions whereupon discrepancies between the angular positions detected by each further control unit and the first control unit are used to generate correcting factors etc. so that the position of the butterfly valve can be detected with substantially equal accuracy in all control units. |
