For a predetermined interval following start-up, a correction is applied to the oscillating output signal for the oxygen concentration as measured by a ceramic cell or electrode. For a predetermined interval following start-up, a correction is applied to the oscillating output signal for the oxygen concentration as measured by a ceramic cell or electrode. The correction factor may be interpolated from a time dependent data base by inputting the oxygen partial pressure, lambda value, and temperature of the exhaust gas. Alternatively, an exponential or polynomial expression can be used to calculate a correction factor using these parameters.
