My truck is displaying DTC PO403 (EGR) Valve Position Control Circuit. Truck surges a little at steady throttle. Anyone have any info or explaination on this condition. Is it OK to drive until I can get it to the dealer on Tuesday? Is there a fix I can do myself to remedy this?

 

you can drive it. Most likely they will have to order parts so be prepared to be down for a day or two. Its an electronics issue. Mine had it for several miles before I could get it in. I didn't even know that was the problem.

Have them give you a rental truck.
