To try to make a long story short, my buddy bought this truck 15,000 miles ago and the dealership installed new nox sensors and a new particulate filter in hopes to try to fix an engine light. It did not and ended up needing the DEF injector. The truck was good for about a year and he got the same code again and after trying to follow a diagnostic video, I thought his number two nox sensor went bad so I replaced it. And his code came back again and it actually needed the DEF injector again. So I’m just trying to recoup a few dollars for my buddy because I installed a new nox sensor and I can’t return it now. The truck is a 2018 Silverado 2500 Duramax diesel. The sensor is OE GM genuine nox sensor position two ( located after the DPF)

These go for about $250 new from the dealer ship. I’d be happy if I can get $75 for this sensor. It only has 15,000 miles on it.
