A diagnostic system for an exhaust system of an internal combustion engine is disclosed. The diagnostic system comprises a catalyst component and a marker that undergoes a physical transition above a transition temperature of the marker. A method for determining if a catalyst component in an exhaust system for an internal combustion 5 engine has been exposed to a deactivating temperature is also disclosed. L'invention concerne un système de diagnostic pour système d'échappement de moteur à combustion interne. Le système de diagnostic comporte un composant catalytique et un marqueur qui subit une transition physique au-dessus d'une température de transition du marqueur. L'invention concerne également un procédé pour déterminer si un composant catalyseur dans un système d'échappement pour un moteur à combustion interne 5 a été exposé à une température de désactivation.
