<p>Disclosed is a malfunction method and system for an output shaft rpm sensor of a transmission. The method comprises the steps of: detecting output shaft rpm of a transmission by the output shaft rpm sensor, and detecting vehicle speed by a vehicle speed sensor; determining whether malfunction conditions, which indicate a malfunction in the output shaft rpm sensor, are satisfied based on the output shaft rpm and the vehicle speed; performing stand-by for a predetermined stand-by time if the malfunction conditions are satisfied; determining whether there is a malfunction in the output shaft rpm sensor using the detected output shaft rpm; and generating malfunction codes if it is determined that there is a malfunction in the output shaft rpm sensor. The system comprises a vehicle state detector for performing detection of various drive states and operations of elements of a vehicle, and outputting corresponding signals, and an ECU for performing the method.</p> |
