摘要：
A method and system for controlling an EGR valve for a vehicle may include an adjusting step of reducing the amount of air flowing into an engine at operation points of the engine lower than a predetermined value at each of the operation points by a controller; a learning step of maintaining, as a reduction-learning amount, a reduction amount of the amount of air from the predetermined value before a malfunction occurs, by the controller, when a malfunction occurs in the engine due to the reduction in the amount of air; a compensating step of determining a compensating air amount at each of the operation points by applying the reduction amount to the predetermined value by the controller; and an EGR controlling step of controlling an EGR-opening amount to satisfy the compensating air amount for a current operation time after the compensating step.
