Abstract: A method for detecting a first rotation angle of a first shaft of an engine is provided, whereby a first marking carrier with sensor-readable markings is provided, whereby the markings form a first marking pattern that has marking sections having at least one first and a second marking section. The first marking carrier is scanned by a first sensor and a first sensor signal is generated. The first sensor signal is modulated by the markings on the marking carrier. A correlation between a time course of the first sensor signal and a time signal is made by a computing unit. A first marking section is recovered from the first sensor signal by the computing unit, and then, a first exclusion criterion for excluding the first stored marking section is determined from the recovered first marking section. The first stored marking section is then excluded by the first exclusion criteria.
