My truck is currently parked onthe side of hwy85. Ths morn on my way to work while accelerating to get on the hwy I lost all power and it started smoking(badly) snow white smoke with surging also going on. I'm guessing oil? My outlook monitor is throwing codes po404 and po 603. Will and EGR valve cause this? Please help

Dude, I cant pull the codes for you but I am sure someone here can. Sounds like what happened to one of our trucks and it was a VGT and EGR

egr valve is hung wide open , replace it dont try and clean it

[DuraWhat?]

Cool, Is there anything I need to watch out for while doing this?

[SCUFFY828]

nope just replace it clear codes and drive it

I would say make sure you go down evenly with the EGR valve so you dont tear one of those o-rings... And if its really wet black tar looking down there, you might be having a EGR cooler problem..

Here are the codes.
P0404 EGR Circuit Range/Performance and P0603 Powertrain Control Module KAM Test Error.

I know it is an old thread,

But I recently had this problem too.

It was my EGR cooler that went bad and the snow white smoke was my coolant being burned. It alsmost overheated the truck because it ran so low on coolant. Figured I'd help any one else out that may have this problem.

OK, Here I go, Don't laugh to hard after you read the question.
I was not aware that the EGR had a cooler. I am having the same problem as above - white smoke, no power after 30 feet and so on.
My question is:
1 - Where is the EGR cooler? I did not see it when I was looking today.
2 - Is this a common problem? If so what can I do to eliminate this happening again?
3 - I know it was mentioned not to try to clean it, Don't try to clean it because it will not become clean or is it just a waste of time?

I just started to have problems witht he truck after 4 years and had to be towed home a few days ago. What a problem that was with an enclosed trailer hooked up. I thought I died due to a clogged fuel filter. I changed the fuel filter on the side of the road with a flash light (10pm). Then the truck started and I took off like I was being chased. Well, About 1,000 feet later I died again. Thinking that I lost the prime due to alot of fuel coming out with filter. I had it towed home.

I am wondering if this was caused by the EGR. The CEL came on a few hours earlier with P0404. What a week.

Thanks,
Rob
