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 5):
The system of  claim 1 , wherein the determined GPF status is indicative of one of the following operating conditions: (i) normal operation, (ii) time to regenerate the GPF, (ii) an overloaded GPF, (iv) a burnt-through or cracked GPF catalyst, and (v) an empty GPF can.
