ABSTRACT:
A device for detecting deterioration of a catalyst temperature sensor which detects the temperature of a three-way catalyst arranged in the exhaust pipe of an internal combustion engine, judges that the sensor has deteriorated when the difference between the actual output value from the catalyst temperature sensor and a reference value based on predetermined engine operating parameters exceeds a predetermined value while the engine is in a predetermined operating condition.
