Abstract

Methods and systems are provided for determining soot stored in a particulate filter and regenerating the particulate filter. In one example, a method provides for operating oxygen sensors in a way that allows water in exhaust gases to be determined. The water in exhaust gases may be a basis for determining an amount of soot stored in a particulate filter.
