Abstract:
A diagnostic system and method for a gasoline particulate filter (GPF) of an exhaust system of a vehicle comprise at least one heater associated with at least one oxygen (O2) sensor disposed proximate to the GPF in the exhaust system and a controller configured to determine a status of the GPF based on a duty cycle of the at least one O2 sensor heater and, based on the determined status of the GPF, detect a malfunction of the GPF or whether to regenerate the GPF.

Claim (Index 10):
The method of  claim 9 , wherein:\n the at least one heater comprises (i) an upstream heater associated with an upstream O2 sensor disposed upstream from a catalyst of the GPF in the exhaust system and (ii) a downstream heater associated with a downstream O2 sensor disposed downstream from the catalyst of the GPF in the exhaust system; and the controller is configured to (i) determine the status of the GPF based on duty cycles of the upstream and downstream O2 sensor heaters and (ii) based on the determined GPF status, detect the malfunction of the GPF or whether to regenerate the GPF.
