  • Patent number: 11959877
    Abstract: In a gas sensor, oxygen pumping control is performed to pump oxygen from the surroundings of an outer side pump electrode into the surroundings of a reference electrode. In addition, during execution of the oxygen pumping control, a pump current Ip2 is measured when oxygen originating from NOx is pumped out from the surroundings of a measurement electrode so that a voltage V2 reaches a target voltage V2*. Then, the NOx concentration of a measurement-object gas is calculated based on Ip2. In the gas sensor, the NOx concentration is corrected based on DVref which is the difference between Vref1 and Vref2, wherein Vref1 is the voltage across the reference electrode and the outer side pump electrode when the oxygen pumping control is not performed, and Vref2 is the voltage across the reference electrode and the outer side pump electrode when the oxygen pumping control is performed.
