Abstract
A method for altering an operating condition of a filter includes actively increasing the temperature of the filter to a desired temperature below a regeneration temperature and sensing a filter operating condition at about the desired temperature. The method also includes comparing the sensed filter operating condition to an expected filter operating condition range and actively increasing the temperature of the filter to the regeneration temperature in response to the comparison.
