Abstract:
A control system includes a temperature determination module and a catalyst protection module. The temperature determination module determines a temperature of exhaust gas based on a resistance of a heating element of an oxygen sensor. The catalyst protection module adjusts an operating parameter of an engine to decrease the temperature of the exhaust gas when the temperature of the exhaust gas is greater than a threshold temperature. The threshold temperature is based on a temperature that damages a catalyst in an exhaust system.
