摘要： A method for dynamically diagnosing an exhaust gas probe. A target/actual comparison is performed between a calculated O2 signal and an O2 signal measured with the exhaust gas probe, for a step load transition. A device for dynamically diagnosing an exhaust gas probe disposed in an exhaust duct of an internal combustion engine. An output signal is fed to an engine controller connected to additional input signals providing information about intake air mass and fuel metering. The engine controller comprises devices for determining a calculated O2 signal from the information about the input air mass and the fuel metering and devices for filtering and/or gradient forming and/or integrating the calculated O2 signal and an O2 signal measured by the exhaust probe. A target/actual comparison between the calculated O2 signal and the measured O2 signal, can be performed for a step load transition.
