<p>To enable rapid sensing of a fault in an oil pressure sensor system after a start of an engine while suppressing an increase in the number of parts of an ECU in a device and a method for oil pressure sensor fault sensing for a vehicle. An oil pressure sensor fault sensing device for a vehicle includes a time measuring section (meter control section (12)) functioning as a sleep mode even while power to an ECU (3) is off, wherein the time measuring section measures a stop time of an engine (1) during the sleep mode, and transmits information on the stop time to the ECU (3) when the power to the ECU (3) is turned on, and when the ECU (3) determines that the stop time of the engine (1) is a predetermined time or more on a basis of the information from the time measuring section to perform fault sensing for an oil pressure switch (2) in a state of the engine (1) not generating an oil pressure, the ECU (3) performs the fault sensing for the oil pressure switch (2).</p> |
