Abstract
A method for diagnosing the function of an exhaust gas sensor in an exhaust gas. The function is evaluated here according to whether during a heating phase an operating temperature of the exhaust gas sensor has been reached for a predefined time period. It is taken into account here whether during the heating phase sufficient heating power has been available to carry out a successful heating phase.
