Abstract: PURPOSE: A catalyst diagnostic device and a method of a vehicle are provided to improve the accuracy of the catalyst diagnosis by sensing the performance degradation of a rear oxygen sensor and analogizing the deterioration of a catalyst by measuring the heat emitting reaction generating in a catalyst through the tip temperature monitoring of an oxygen sensor. CONSTITUTION: A catalyst diagnostic device of a vehicle is composed of an engine(10), a catalyst(20), a controller(40), and a rear oxygen sensor(30). The engine generates the power through the combustion. A noble metal is mounted inside the catalyst. The catalyst purifies the harmful material by reacting about the harmful material included in the exhaust gas and the oxidizing and reducing materials. The rear oxygen sensor is arranged in the outlet of the catalyst. The rear oxygen sensor outputs the oxygen content according to the richness/lean of the mixing ratio as the switching signal. The catalyst output temperature is measured by detecting the internal resistance value of the rear oxygen sensor. The difference of temperature is calculated by calculating the exit temperature by the exothermic reaction. The controller judges the malfunction by the deterioration of the catalyst by comparing the calculated value with the limit value of the malfunction decision.
