Abstract
A control system includes a temperature determination module and a heater control module. The temperature determination module determines a temperature of an oxygen sensor in an exhaust system of an engine. The heater control module applies a heat cycle to combust deposits on the oxygen sensor by activating a heating element of the oxygen sensor to increase the temperature of the oxygen sensor to greater than 800 degrees Celsius.
