Abstract
A sensor for use with a diesel particulate filter in an exhaust system includes a collection device configured to be positioned downstream of the diesel particulate filter such that particulate matter not captured by the diesel particulate filter accumulates on the collection device. The collection device is configured to visually indicate a rate of particulate matter accumulation on the collection device. The rate of particulate matter accumulation corresponds to filter performance.
