Hi - just joined up - having some new service codes showing up at 50,000 km on 2017 Ram 1500 Big Horn.
UO402 - invalid transmission control unit data. 1st time code
P20EE- Nitrogen oxide (NOx) sensor, catalyst, bank 1 - efficiency below threshold- have had this 3 or 4 times
truck running fine - since these issues have probably happened several times to other trucks thought I would put it out there hoping there might be a DIY fix.
