Abstract
Methods and systems are provided for diagnosing the presence or absence of a catalyst substrate within a catalyst can or housing. The methods and systems described a persistence of excitation metric that is a basis for judging whether or not the catalyst can is empty. If it is determined that the catalyst can or housing is empty, mitigating control actions may be performed via a controller.
