ABSTRACT:
A method of correcting an output of a NOx sensor including: a first step of obtaining a sensor-variation relational expression based on a relationship between an Ip2/Ip0value and an output change percentage for a calibration sensor; a second step of obtaining, from the relational expression, an output change percentage β that corresponds to an Ip2/Ip0value of a subject NOx sensor; a third step of calculating a pressure correction coefficient α based on the obtained β; and a fourth step of performing output correction on the subject NOx sensor by calculating the pumping current Ip2(p0) under a reference pressure based on the pumping current Ip2(p) and a pressure p of the measurement gas which are detected upon measurement of the NOx concentration in the measurement gas.
