Zusammenfassung:	Systems and methods for diagnosing an exhaust aftertreatment system and mitigating the effects of a potential fault in the exhaust aftertreatment system are provided. A method includes: receiving, by a controller, data indicative of an amount of at least one of a gain or an offset affecting a sensor in an aftertreatment system; determining, by the controller, a compensation value based on the amount of the at least one of the gain or the offset; receiving, by the controller, data indicative of an amount of an exhaust gas constituent in the aftertreatment system; applying, by the controller, the determined compensation value to the data indicative of the amount of the exhaust gas constituent in the aftertreatment system to create compensated data; and initiating, by the controller, an action based on the compensated data.
