    • PURPOSE: A catalyzed particulate filter monitoring method in a diesel vehicle is provided to directly monitor a CPF mounted on a diesel vehicle according OBD-II regulation on NMHC using the temperature difference of temperature sensor mounted on the front end and the rear end of the CPF. CONSTITUTION: A catalyzed particulate filter monitoring method in a diesel vehicle comprises following steps. The post injection is performed(S16). The temperature sensed by a front temperature sensor and a rear temperature sensor mounted on the front end and the rear end of a catalyzed particulate filter is read(S18). The temperature difference of the front temperature sensor and the rear temperature sensor of the catalyzed particulate filter is calculated(S20). The change rate of the temperature difference is calculated by deducting temperature difference of the previous step from the temperature difference. Whether the change rate of the temperature difference exceeds critical value or not is determined(S24). In case the change rate of the temperature difference does not exceed the critical value, OBD-II regulation fault code on the catalyzed particulate filter is generated(S28).
