check engine light

I have a 06 f250 king ranch with 6.0 . A few days ago my scangauge showed a code

p0405

I changed my egr and after it showed two codes

p0405 and p0404

It still has a hesitation and loss of power , although better than before the
Change.

Any ideas?

Wiring harness look ok? Maybe there is a problem with the replacement EGR valve. Do you have any diag equipment that can read live data?

Ah yes...I hate it when I do that.

Try checking these:

EVD

EVM
