PURPOSE: A method for disposing exhaust gas is provided to precisely detect the damage of a diesel particulate filter using differential pressure between the front and the rear end of the diesel particulate filter. CONSTITUTION: A method for disposing exhaust gas includes: a step of calculating the model amount of a sensor collecting particulate collected by a particulate sensor(140) under the normal condition of a diesel particulate filter(130) based on a condition for engine driving and the variation of the condition; a step of calculating the actual amount of the sensor collecting particulate attached to the particulate sensor using the actual signal of the particulate sensor; and a step of the status of the diesel particulate sensor by comparing the model amount of the sensor collecting particulate and the actual amount of the sensor collecting particulate.
