用于排气流体传感器的方法
摘要：
本发明提供的多个方法用于诊断排气流体通道中设置的排气流体传感器。通过在当与排气流体接触时以及不与排气流体接触时的工况期间监测传感器，可监测传感器输出中期望的改变以识别传感器当前是否产生足够精确的读数。
摘要（英）：

Various methods are provided for diagnosing an exhaust fluid sensor disposed in an exhaust fluid passage. By monitoring the sensor during conditions when it is in contact with the exhaust fluid and when it is not in contact with the exhaust fluid, an expected change in the sensor output can be monitored to identify whether the sensor is generating sufficiently accurate readings.
