A control method of an exhaust gas purification system for a vehicle may include: determining, by an injection controller, whether a selective catalyst reduction (SCR) is actuated; determining, by the injection controller, whether a temperature of the SCR is within a set diagnosis region; deciding, by the injection controller, a normal pattern of the SCR corresponding to the temperature of the SCR; comparing, by the injection controller, the decided normal pattern of the SCR with a current performance pattern of the SCR; determining, by the injection controller, whether a current performance pattern of the SCR is an abnormal pattern; and performing, by the injection controller, a correction control based on a current abnormal pattern of the SCR.
