20200088665 · 2020-03-19 ·

In a gas sensor diagnosis device, a temperature change part varies a temperature of a sensor element in an ammonia sensor at a first temperature which is outside of the predetermined activation temperature range. A zero-voltage shift detection part detects whether the mixed potential of the sensor element is not more than a predetermined output threshold value after the temperature change part varies a temperature of the sensor element. A temperature acquisition part detects a zero-voltage shift temperature of the sensor element at which the zero-voltage shift detection part detects that the mixed potential of the sensor element drops below the predetermined output threshold value. The deterioration state detection part detects a deterioration state of the ammonia sensor based on the zero-voltage shift temperature of the sensor element detected by the temperature acquisition part.
