<p>A method and a system that diagnose failure of an oil pressure sensor that senses or detects an operating oil pressure in a target device (e.g., a hydraulic clutch) using oil pressure. The method includes a controller that is configured to store an ignition off time that an ignition is turned off and detect an ignition on time that the ignition is turned on after the ignition has been turned off. In addition, the controller is configured to calculate an elapsed time from the ignition off time to the ignition on time and determine whether the elapsed time is equal to or greater than a predetermined time. When the elapsed time is equal to or greater than the predetermined time the controller is configured to diagnose oil pressure sensor failure and when the elapsed time is less than the predetermined time, stop diagnosing failure of the oil pressure sensor.</p> |
