I have codes U059E, P2202, P2209 which I believe is the upstream/intake NOX sensor, but where the heck is this thing? All the videos I'm seeing are for 4th gens and earlier. I'm assuming it's just downstream of the turbo, but I haven't gotten in there, yet. Don't want to tear off the wheel well liner if I don't need to. Any help would be greatly appreciated.
