A method for operating an internal combustion engine in the event of a fault in a crankshaft sensor is provided, the internal combustion engine having at least two camshafts and a speed and/or a position of the internal combustion engine being derived from a signal taken from the camshaft. In order to improve the exhaust gas performance of the internal combustion engine even in a crankshaft emergency operating mode, only a first camshaft is used to determine the speed and/or the position of the internal combustion engine, while the second camshaft. is adjusted in its angle of rotation in order to set a variable valve operating mechanism on the intake and exhaust valves of the internal combustion engine that are driven by the second camshaft. |
