PURPOSE: A method for learning the operation of a valve is provided to improve stability by preventing a gas leak, and to secure stable airtightness of a valve body. CONSTITUTION: A method for learning the operation of a valve is as follows. When an engine is started(S101), a valve is operated based on a pre-set control current value(S102). When the valve is maximally operated, it is determined whether the flow of the valve is generated(S104). When the valve is fixed(S106), the control current value is renewed(S107).
