1996 Mercury Sable trying to find my DPFE sensor or Duralas

Hi, i received an p401 code and got the EGR valve replaced (tried cleaning it but still go the code). I read that the next thing to test would be the dpfe sensor but i can seem to locate it on my car, i have a pretty good idea but some confirmation would be very helpful. I circled what i believe is the part (bottom mid right).


Any help is greatly appreciated

Thanks
