Abstract

A method and system for making available an improved phase signal of a phase sensor on a camshaft of an internal combustion engine immediately after switching on the phase sensor and/or the internal combustion engine are provided. In this context, the phase sensor scans the angle marks of a signal-generating wheel that is connected to the camshaft in a torsionally fixed manner. In addition, a crankshaft sensor scans the angle marks of a signal-generating wheel that is connected to the crankshaft in a torsionally fixed manner.
