Abstract
A method of monitoring an exhaust treatment system of a vehicle is provided. The method includes: determining a modeled resistance of exhaust flow in the exhaust treatment system; determining a measured resistance of exhaust flow in the exhaust treatment system; evaluating the modeled resistance and the measured resistance to determine a fault status; and generating at least one of a warning signal and a message based on the fault status.
