It's a big if to guess but if its EGT1, it would be a quick job. First have to determoine what sensor it really is.
The description for 004719 is as you say, EGT before the SCR. This makes me think of the 3rd EGT down at bottom of the DPF. Of course you don't have one of those on your downpipe. I agree with earlier poster to see what your 3 EGTs are all reading. You should only see EGT 1 which is just at beginning of the down pipe. I'm scratching head here too.
