摘要
Systems and methods for diagnosing operation of a catalyst are presented. In one example, threshold limits for catalyst variables are adjusted in response to attributes of a catalyst monitor sensor that may vary with sensor age. The catalyst variables may provide insight into whether or not the catalyst is degraded or operating as intended.
