My truck is throwing P0401 and P0402. I believe this would be a bad EGR . But its only a year old (the EGR). Does anyone have any other thoughts on what could be causing the codes. Thank you for the help.

So I presume you have already scanned it with a code reader? The best I can come up with by googling those codes is an EGR.. So my guess would be that nothing else could be the problem.. however it coudl be either the EGR valve or maybe one of the tubes for the egr is plugged up...
