System and method for excluding false back pressure faults after installation of a particulate trap filter |
摘要 |
A method and system for preventing or minimizing false back pressure faults caused by a new particulate filter in an engine exhaust system. When a new particulate filter is placed in an engine exhaust system, the normal back pressure threshold for the fault detection system is increased by a new filter offset amount. Back pressure faults at the normal level are not recorded for a limited period of engine operation and only records back pressure faults that exceed the normal back pressure threshold by the value of the new filter offset.
