Failure diagnosis apparatus for temperature sensor










Image Number 11 for United States Patent #6980904.

A failure diagnosis apparatus for a temperature sensor which detects a temperature that changes depending on an operating condition of an internal combustion engine. Determining that the temperature sensor fails, if the execution condition of the failure determination is satisfied and a temperature difference between the maximum temperature and the minimum temperature detected by the temperature sensor in the determination period, is less than a failure determination threshold value, when the starting of the engine in the preceding engine operation cycle was a cold start. Alternatively, determining that the temperature sensor fails, if the execution condition is satisfied, the temperature difference between the maximum temperature and the minimum temperature is less than the failure determination threshold value, and an engine stop period in the preceding engine operation cycle is longer than a failure determination permission time period, when the starting of the engine in the preceding engine operation cycle was not a cold start.
