It’s the easiest thing in the world to look at the pie and see if it’s done. No need to stick things in it.

Oh man, are you having to sit in a kitchen somewhere witnessing this? I have never, ever taken the temp of a pumpkin pie. I have cooked so many, usually two at once. Once the middle is just setting, you can pull it out. It will continue to cook. Just a couple of wiggles to the plate will let you tell visually the set status.

175F. No need to keep sticking a fork or knife in it.
