Abstract: The present invention relates to a method for diagnosing a failure of a power stage of an electronic waste gate actuator (EWGA). According to the present invention, whether the failure of the power stage of the EWGA occurs is determined by confirming, by an engine control unit (ECU), information on the failure of the power stage transferred from an EWGA driver IC at the time of EWGA position learning, after an engine is turned off. By doing so, even when a turbo-charger is not used for a long time, whether the failure of the power stage of the EWGA occurs may be diagnosed for every driving cycle, such that a failure of the ECU may be prevented in advance and unnecessary replacement of components may be prevented, thereby decreasing maintenance costs for a vehicle.
