Abstract
A fault sensing device for a vehicle includes a time measuring section functioning as a sleep mode while power to a controller is off. The time measuring section can measure a stop time of an engine, and can transmit information on the stop time to the controller when power to the controller is on. When the controller determines that a stop time of the engine is a predetermined time, the controller performs fault sensing for an oil pressure switch.
