Abstract
A method for diagnosing the dynamic characteristics of a lambda sensor, which is used at least intermittently for a cylinder-individual lambda closed-loop control, which provides for at least one actuating variable of the lambda closed-loop control to be detected and compared to a specifiable maximum threshold, and, if the maximum threshold is exceeded, the dynamic response of the lambda sensor is deemed insufficient with respect to the usability for the cylinder-individual lambda closed-loop control.
