Abstract
A method and system for improving sensor accuracy of diesel emissions is disclosed. The method and system comprises changing the sensor reading as a function of sensor age to provide a more accurate measure of the diesel emissions. By estimating the degree of sensor error and then providing a gain correction factor as a function of sensor age, a more accurate measure of the diesel emissions is provided.
