Abstract

Systems and methods for diagnosing a catalyst of an aftertreatment system is described herein. The system includes an exhaust aftertreatment system and a controller coupled to the exhaust aftertreatment system. The controller receives a dosing efficiency regarding a catalyst of the aftertreatment system and determines an actual aging condition of the catalyst based at least in part on the dosing efficiency. The controller further include receives temperature data indicative of an operating temperature of the catalyst, the temperature data having associated runtime durations and determines an expected aging condition of the catalyst based on the temperature data and the associated runtime durations. The controller transmits an early aging notification to a user device in response to the actual aging condition exceeding the expected aging condition.
