Abstract

A method of operating an internal combustion engine in a motor vehicle has the steps of determining angular positions of a crankshaft and a camshaft from signals of two detecting devices, monitoring a relative angular position of one of the shafts relative to the other of the shafts, and, depending on whether a change of the determined actual relative position is located outside the tolerance region, releasing an action, and also a computer program, a storage medium, a control and/or regulating unit, and an internal combustion engine with the use of inventive method are proposed.
