ABSTRACT:
A method of detecting abnormality in an internal combustion engine, which is applied to at least one of a catalyst system, an evaporative fuel-purging system, a fuel supply system, an air-fuel ratio sensor, and an ignition system, for performing detection of abnormality therein according to operating parameters of the engine. An amount of residual fuel in the fuel tank is detected and the amount of residual fuel is compared with a predetermined value. The abnormality detection is inhibited when, as a result of the comparison, the amount of residual fuel is below the predetermined value.
