Abstract

Methods and systems are provided for adjusting an ammonia (NH) sensor output using readings of a nitrogen oxide (NOx) sensor, the NOx sensor having a sensitivity factor to NH. In one example, a method may include determining and updating a gain value of the NHsensor during zero NOx conditions to be used to calculate a corrected NHsensor output value, and determining and updating an offset value of the NHsensor during zero NHconditions to be used to zero the NHsensor during zero NOx conditions.
