  • Oil temperature sensor diagnostic device
    Patent number: 10920629
    Abstract: An oil temperature sensor diagnostic device is configured to detect an abnormality in an oil temperature sensor provided in a vehicle, the vehicle including the oil temperature sensor configured to detect an oil temperature of a lubricant of an engine, and an idle-stop controller configured to execute an idle-stop control. The oil temperature sensor diagnostic device includes: a diagnostic value setting module configured to set a diagnostic value that is increased according to an elapsed running time; and an abnormality determination module configured to determine an abnormality of the oil temperature sensor in a case in which a rise in the oil temperature computed on a basis of an output of the oil temperature sensor is small compared to an amount of increase in the diagnostic value.
