Abstract

Systems, apparatuses, and methods for monitoring a catalyst health parameter are provided. A system includes one or more processing circuits having one or more memory devices coupled to one or more processors. The one or more memory devices store instructions that, when executed by the one or more processors, cause the one or more processors to: receive information indicative of at least one of a temperature of exhaust gas entering the aftertreatment system, a time at idle, or a mass flow of exhaust gas; determine a catalyst health management criteria based on the information; determine a catalyst health indicator based on the catalyst health management criteria being met; compare the determined catalyst health indicator to a predetermined health threshold criteria; and provide a notification based on the determined catalyst health indicator being less than the predetermined health threshold criteria.
