Fault Code Description |
---|
Monitoring of the correction factor for nitrogen oxide sensor downstream of SCR catalytic converter. The fault is set when: - The NOx correction factor (gradient) does not lie between the lower and upper limit. - The NOx correction factor (deviation) does not lie between the lower and upper limit. Lower limit (gradient): 800 Upper limit (gradient): 1200 Lower limit (deviation): -200 Upper limit (deviation): 200 |
