Abstract
An engine ECU executes a program including the steps of: when the port fuel injection ratio is 100% (YES at S), sensing the engine coolant temperature THW (S); when the engine coolant temperature THW is higher than a threshold value (YES at S), monitoring fuel pressure P in a high-pressure delivery pipe (S); and when fuel pressure P rises by the received heat (YES at S), identifying that there is no error at the high-pressure fuel system.
