No, no, no. Never, ever, ever, ever go by what the guys at AutoadvancepepO'ReillysboysZone tell you. They're out to sell parts before anything else. I think he really meant EGR valve, in which case I'll go ahead and reach out and say he's wrong, these EGR valves don't fail very often. Tote it back to 'em, get it rescanned and find the exact number of the code. There's a few common failure items when it comes to the EGR system in that engine (and these trucks in general), and we can better pinpoint what you need to do with the specific code. Without that code, we'd be throwing parts at it hoping for the best, which gets annoying and expensive.
