Abstract
An on-board diagnostics system for an exhaust system of an internal combustion engine is disclosed. The system comprises a catalyzed substrate having a catalyzed region and an uncatalyzed region, a first sensor, and a second sensor. The first sensor is located within the catalyzed region of the catalyzed substrate and the second sensor is located within the uncatalyzed region of the catalyzed substrate. A method for on-board diagnostics of the catalyzed substrate is also disclosed.
