A method for detecting breakage of a diesel particulate filter (DPF) for detecting a tiny breakage of the DPF may include obtaining a learned value of a flow resistance in the DPF when a regeneration of the DPF is terminated, calculating a predicted value of the flow resistance, determining whether the learned value is within a permissible error range of the predicted value, and determining that the DPF is broken if the learned value is not within the permissible error range. The method may further include storing an arithmetic average of the learned value according to a mileage of a vehicle and transforming a relation between the mileage and the learned value to a polynomial expression.
