Abstract
A sensor which detects whether or not an engine output shaft and a vehicle drive shaft are in a predetermined connection state, is subjected to a fault determination when a predetermined condition holds. When the engine output shaft and vehicle drive shaft are constantly in this connection state from when the engine starts to when the above condition comes to hold, it is determined that a fault has occurred in the sensor. It is also determined whether or not the vehicle is running when the engine starts, and when the vehicle is running when the engine starts, fault determination is prohibited so as to avoid incorrect results.
