Abstract
An exhaust gas sensor and a method for determining concentrations of exhaust gas constituents are provided. The exhaust gas sensor includes a NONernst cell that generates a first voltage indicative of a NOconcentration in the exhaust gases communicating with the NOsensing electrode. The exhaust gas sensor further includes a NONernst cell that generates a second voltage indicative of a NOconcentration in the exhaust gases communicating with the NOsensing electrode. The exhaust gas sensor further includes a NHNernst cell that generates a third voltage indicative of a NHconcentration in the exhaust gases communicating with the NHsensing electrode.
