ABSTRACT:
The invention relates to a method and apparatus for diagnosing an abnormality in an internal combustion engine fuel temperature detection apparatus, by comparing fuel temperature detection values with other detection values for cooling water temperature and intake air temperature. The arrangement is such that when there are large changes in the detection values for the respective temperatures, diagnosis is interrupted, thus enabling the prevention of erroneous diagnosis at the time of hot start and the like when changes in the respective detection values are large.
