Error Codes P0407 P0488
Hey guys,
So I am totally new to 6.0 engines and trucks in general. I have done a lot of reading and I am still in the dark about what could be wrong with my engine.
I got my first OBD-II scanner today and it threw the codes p0407 and p0488. I have no idea how long they have been there. After doing quite a bit of reading I know it has to do with the EGR and has to do with the sensor and plate. However, my truck is completely stock and most of the places I have read all have had the EGR deleted, so I am confused.
Here are the exact codes:
P0407 - Powertrain
Exhaust Gas Recirculation Sensor "B" Circuit Low
P0488 - Powertrain
Exhaust Gas Recirculation Throttle Position Control Range/Performance
Online it said that there is often white smoke associated with these codes. I had white smoke last night but after asking over in the Excursion forum what the cause could be the general consensus was the cold (-13 F) was the cause of the smoke. Could the cold also cause this?
I am sorry if the answer is right infront of me, I've been known to walk into the only tree in the field.
Also, this might not be related at all, but I am due to change my oil later this week. I just recently bought the truck from my parents and realized that it has been 9500 miles since the last oil change.
Cheers,
Nate
PS - Is the truck driveable? I mean should I be driving it... I drove it today no problems but like I said I really have no idea.

So I did all my research and prepared to dive in to do the cleaning... and as soon as I apply the tiniest bit of pressure to the head of the bolt it just falls off. Almost like it was not even attacked.
I watched 3 youtube videos showing me how to do the cleaning, hope up to do it and don't even get 3 seconds in....
Turns out that its just the head missing (ugh) and I am going to need to drill it out I guess. I'll have to seek my Uncle's help since I was already out of my newbie comfort zone... Is the truck still driveable? Or will he need to come to me rather than I to him??
Thanks,
Nate
EDIT - It was also super grimy and gummy around the valve... could this mean that it has been leaking?

Have been seeing a tonne of white smoke at startup but was told this could be to rally cold starts.

Here's a vid of the coolant levels and what I mean in terms of the gunk around the EGR valve. You can see a lot of it around the valve in the picture above.
Thanks for the help guys... I know alot of you are probably just shaking your heads but I am trying to get into this whole "maintaining" thing haha. Want to keep it around for a long time so better late than never.

I will let you know about the inside, but yes the gunk is all around the EGR valve. Too scared to go after that second bolt until I get it to my uncles. Thanks for all your help. Reps for you all.

1. Blown EGR COOLER
2. HEADS / Crack in Heads ( hair line).
take PRE Caution .
look at EGR cooler Hose in the Valley
look at Head moister passerger side Block# 7 port
Watch level in Degus ( smell or Test).
DO not Drive the truck .
