engine malfunction light on
 

Hello everyone, I have an engine light on my dashboard, I put diagnostic scanner I have the error code p20ee-04, p20ee92 -p20ee97 and p229f-28. I got the selective catalytic reduction control system interface working,


1.diesel exhaust fluid additive pressure ok
2.nox sensors online ok
3.active ammonia storage not...
I think it is the nox sensor that is faulty because it is the one that gives information on the storage of ammonia in the scr converter to the computer zero information to the scanner and in addition error code p229f-28 what do you think?
