Abstract
An ECU executes a fuel cut-off time ignition process that causes the ignition device to generate a spark discharge during a fuel cut-off for temporarily stopping fuel injection of the fuel injection valve. The ECU determines that the fuel injection valve is stuck open when a rotation fluctuation amount of an internal combustion engine during execution of the fuel cut-off time ignition process is greater than or equal to a predetermined stuck-open determination value.
