Abstract
A system for determining a temperature of exhaust gases from an engine is provided. The system includes an exhaust gas sensor having an electric heating coil. The sensor communicates with exhaust gases from the engine. The system further includes an electrical circuit for generating a signal indicative of the resistance of the heating coil when the coil is not energized. Finally, the system includes a controller receiving the signal and calculating the temperature of the exhaust gases based on the signal.
