ABSTRACT:
A method of monitoring engine performance as a function of soot accumulation in a particulate filter includes determining characteristics of soot accumulation in the filter, analyzing the characteristics, and generating an error signal if the characteristics are indicative of predetermined engine performance conditions. An electronic controller configured to monitor soot accumulation in such a manner is also herein disclosed.
