| description | The invention relates to a method for detecting at least one exhaust gas sensor (22; 22 ') arranged in an exhaust gas channel (21) of an internal combustion engine (10). 24; the invention relates to a method for diagnosing an internal combustion engine (10) having an exhaust gas duct (21), in which ambient air (12) can be actively introduced into the exhaust gas duct (21) by means of a device (27), in which ambient air (12), in particular oxygen, is actively introduced into the exhaust gas duct (21) by means of the device (27) if there is an operating state in which the internal combustion engine (10) does not provide an exhaust gas mass flow, wherein a diagnosis is subsequently carried out on at least one exhaust gas sensor (22, 24, 26) arranged in the exhaust gas channel (21).
本发明涉及一种用于对内燃发动机（10）的至少一个布置在废气通道（21）中的废气传感器（22；24；26）进行诊断的方法，其中能够借助于装置（27）主动地将环境空气（12）引入到所述废气通道（21）中，其中，如果存在所述内燃发动机（10）不提供废气质量流的运行状态，则通过所述装置（27）主动地将环境空气（12）、尤其是氧气引入到所述废气通道（21）中，其中随后对至少一个布置在所述废气通道（21）中的废气传感器（22；24；26）执行诊断。 |
