Abstract: An exhaust aftertreatment system may include an oxidation catalyst, a soot sensor, a filter and a control module. The oxidation catalyst may be disposed in an exhaust gas passageway and may receive exhaust gas discharged from an engine. The soot sensor may be at least partially disposed in the exhaust gas passageway downstream of the oxidation catalyst. The filter may be disposed in the exhaust gas passageway downstream of the soot sensor. The control module may be in communication with the soot sensor and may determine a face-plugging condition of the oxidation catalyst based on data received from the soot sensor.
