Abstract
When the driving wind and the cooling wind are generated, based on the phenomenon in which the temperature difference is generated between the front surface and the rear surface of the radiator (), the temperature difference between the detection value of the rear temperature sensor () and the detection value of the front temperature sensor () is compared with the abnormality determination value so that it is determined whether the front temperature sensor () and the rear temperature sensor () are properly fixed on the radiator (), whereby it is determined whether the abnormality (unauthorized alteration) exists. By setting the abnormality determination value according to the ambient temperature and the vehicle speed, corresponding to a variation in temperature difference between the front surface and the rear surface of the radiator (), the abnormality determination value is varied to be set at a proper value.
