METHOD FOR DIAGNOSING BREAKDOWN OF CRANKSHAFT POSITION SENSOR FOR VEHICLE

摘要

The present invention relates to a method for diagnosing an abnormality of a crankshaft position sensor for a vehicle, which comprises the following steps of: determining whether or not an electrical abnormality occurs by measuring a voltage value from the crankshaft position sensor; and determining whether or not a crank signal is abnormal by receiving a signal from the crankshaft position sensor. Accordingly, internal diagnostic information on a smart IC disposed in a control unit of a vehicle can be used to determine whether or not the crankshaft position sensor has an electrical abnormality and the type of the abnormality.;COPYRIGHT KIPO 2018
