ABSTRACT:
An exhaust gas sensor and a method for determining concentrations of exhaust gas constituents are provided. The exhaust gas sensor includes a NO2Nernst cell that generates a first voltage indicative of a NO2concentration in the exhaust gases communicating with the NO2sensing electrode. The exhaust gas sensor further includes a NOxNernst cell that generates a second voltage indicative of a NOxconcentration in the exhaust gases communicating with the NOxsensing electrode. The exhaust gas sensor further includes a NH3Nernst cell that generates a third voltage indicative of a NH3concentration in the exhaust gases communicating with the NH3sensing electrode.
