Truck missing-Codes P1316,P0470,P0478 Help

[jdw196]

Hey guys this really looks like a cool site, I just joined today. I am having a problem with my 99 F250 7.3 . It start running rough just off idle and usually when I would first start it up and take off. The check engine light would come on and then go out all would be fine for a while. I finally got around to changing the oil and fuel filter last weekend. but that didnt help. It was really bad today the light never went out when I went to town. It has a superchip programmer so I plugged it in and got these codes. P1316,P0470,and P0478. I have found a little bit about the harness that might go through the valve covers might be a place to check out the P1316. but I need help. I am new to working on diesels (I have only enjoyed driving this for the las year or two but i just rolled 200,000 and maybe the real fun is just beginning.) Any input would be appreciated. I am going out to check what might be some wiring, the ones going through the valve covers.??? Any help is appreciated and thank you in advance
thanks from a newbie
Jeff

the wiring harness under the valve cover is a common problem with the 7.3L. pop the covers and check the connections.
