<P>PROBLEM TO BE SOLVED: To provide a device and a method for diagnosing the rationality of a sensor in a tank can accurately and easily diagnose whether the rationality of each sensor is maintained or not. <P>SOLUTION: This method for diagnosing the rationality of the sensor in the tank is for diagnosing the rationality of a concentration sensor, a liquid level sensor, and a temperature sensor provided in the tank storing liquid, and diagnoses if any of the concentration sensor, the liquid level sensor and the temperature sensor loses the rationality of the sensor by determining whether there is contradiction in each sensor value detected by the concentration sensor, the liquid level sensor, and the temperature sensor. <P>COPYRIGHT: (C)2010,JPO&INPIT |
