A gas sensor is created comprising an electrochemical cell having a solid electrolyte layer disposed between an exhaust gas electrode and a reference electrode. A resistor is disposed in electrical communication with a heater and the reference electrode. The resistor can be disposed on a side of the gas sensor; on a side of the gas sensor such that the resistor is electrically connected through a via hole; over at least a portion of at least two sides of the gas sensor; or disposed in a void extending at least from the heater to the pump electrode, such that the void extends to at least a surface of the gas sensor, extends to at least partially through the gas sensor, or extends completely through the gas sensor. A method for using this gas sensor comprises applying a voltage to the heater within the gas sensor. A current is directed through the resistor to the reference electrode to pump oxygen into the reference electrode.
