Abstract
Control systems and methods are for a marine engine emitting exhaust gas. A sensor senses a characteristic of the exhaust gas. An electrical heater heats the sensor. A control circuit monitors current drawn by the heater. The control circuit controls an operational characteristic of the engine based upon the characteristic of the exhaust gas and modifies its control of the operational characteristic of the engine when the current drawn by the heater changes by a predetermined amount.
