Hey there. So I recently went to Chevy to get my CEL diagnosed. And the technician told me that the code was for the Nox #2 sensor this time. And I’m just wondering if I have to get that replaced before I do a DPF delete or not. Because I don’t want to spend close to $800 to have that part replaced if it’s part of the DPF because I’ll just be deleting that sensor then.
