A method of manufacturing an exhaust gas sensor allows the manufacturer to selectively control the air-voltage range of the manufactured sensor between a first air-voltage range and a second air-voltage range. The sensor includes a signal wire and a ground wire. The method includes using a high nickel alloy for both of the signal wire and the ground wire to manufacture a sensor in the first air-voltage range, and using a high nickel alloy for only one of the signal wire and the ground wire to manufacture a sensor in the second air-voltage range. The air-voltage ranges are those associated with a lean-application normalized air/fuel ratio of λ>1.
