Abstract
In a method for diagnosing a charge cycle valve stroke adjusting system of an internal-combustion engine having at least one exhaust gas sensor which supplies an output signal continuously varying with an exhaust gas constituent, the spread width of the output signal is determined, and compared with a reference value. Defects of the valve stroke adjusting system are detected on the basis of the comparison.
