METHOD FOR VERIFYING THE FUNCTIONALITY OF THE COMPONENTS OF A DIESEL PARTICULATE FILTER SYSTEM

A method for verifying the functionality of the components for a diesel particulate filter system based upon engine speed, engine torque, inlet and outlet exhaust pressure at the diesel particulate filter. Various sensor signals are compared to calibratable values in memory for a determination wheth...
