摘要：
Failure of a valve timing changeover control system of an internal combustion engine is detected by the steps of: (1) setting a predetermined state of intake air to be supplied to the engine depending on a control signal for controlling changeover of valve timing, (2) detecting a state of intake air being supplied to the engine, (3) comparing the detected state of intake air with the set predetermined state of intake air, and (4) detecting from the result of the combustion whether or not there is failure in the valve timing changeover control system.
