That COULD be damage in the COP/plug areas. It really bugs me, because I like to wash my engine too. I'm really afraid to do much to the engine bay in my truck, due to all the horror stories I read shortly after I got it.

As I posted on f150online when you brought it up over there, I discovered you cannot simply replace the TPS (which was probably toast) on 2004 engines. You have to replace the entire Throttle Body.

For future reference on DTC codes especially multiple ones in a single event.
Try to get them in order of appearance.
It usually the 1st to 3rd that are the indicating ones and the rest can sometimes be redundant.
Peace!

I think taking it to the dealership is the best thing you could do.
