Abstract
A device provided in an exhaust system of an internal combustion engine in order to detect exhaust gas temperature. The device includes an oxygen sensor which has a sense element outboard of a heater element. The oxygen sensor is further designed to incorporate a temperature sensing element on the outboard of the sense element. The temperature sensing element optimizes the detection of the exhaust gas temperature, thereby providing efficient operation of the engine.
