Method for diagnosing error of exhaust gas tube arranged in exhaust channel of internal combustion engine, involves evaluating output signals of exhaust gas tubes for error diagnosis

摘要

The method involves evaluating output signals of the exhaust gas tubes (15, 17) for the error diagnosis, and diagnosing information for interruption of the internal combustion engine (10) or other suitable information for the quiet running or for attaining the combustion limit of the internal combustion engine. The lambda servo control is guided to the combustion limit of the internal combustion engine. An independent claim is included for an apparatus for diagnosing an error in an exhaust duct of an internal combustion engine.
