Disclosed herein are NOx sensors and method of using the same. In one embodiment, a method for sensing NOx comprises: contacting a first NOx electrode (12) with the gas, contacting a second NOx electrode (18) with the gas, determining a NO2 emf between the first NOx electrode and a first reference electrode (14), determining a NOx emf between the second NOx electrode and a second reference electrode (20), and determining a NO2 concentration and a NO concentration using the NO2 emf and the NOx emf. The first electrode (12) can be at a first temperature of greater than or equal to about 700° C, and the second electrode (18) can be at a second temperature of about 500°C to 650 C.
