20090025374	System and Method for Cleaning Combustion Soot from Exhaust Gas Treatment Sensors - A system and method are provided for cleaning combustion soot from an exhaust gas aftertreatment sensor. The system and method determine whether to conduct a sensor desoot event, and if it is determined that a sensor desoot event is to be conducted, the exhaust gas temperature is increased such that the temperature of the sensor correspondingly increases to or above a desoot temperature, the exhaust gas temperature is then controlled to maintain the temperature of the sensor at or above the desoot temperature for a predefined time period, and the exhaust gas temperature is then decreased after the temperature of the sensor has been at or above the desoot temperature for the predefined time period.	01-29-2009
