Oxygen sensors are employed in various applications to determine the oxygen content for a stream of gas as it flows past the sensor. A automotive vehicle is generally equipped with an oxygen sensor, which detects the amount of oxygen in exhaust gas, and produces a voltage signal indicative of the amount of oxygen detected. In automotive applications, an oxygen sensor is typically mounted in the exhaust system of an automotive engine. Oxygen sensor is typically located in the engine compartment and is separate from the interface circuit. The oxygen concentration in the exhaust gas of an engine has a direct relationship to the air-to-fuel ratio of the fuel mixture supplied to the engine. Oxygen sensors provide accurate oxygen concentration measurements of automobile exhaust gases for determination of optimum combustion conditions, maximization of fuel economy, and management of exhaust emissions. An oxygen sensor generally comprises an ionically conductive solid electrolyte material, a sensing electrode that is exposed to the exhaust gas and reference electrode that is exposed to a reference gas, such as air or oxygen.
