Attention: TDR Forum Junkies 
Hello All,
I'm getting the P2201 code, which I understand to be for the upstream NOx sensor. I must be missing something - This post says that after the T05 recall, there's only one sensor, the downstream one. If this is true, since I had my T05 recall done in 2019, how can I be getting a P2201 code if that sensor is no longer there?
