burned DPFE

my wife just got back from a 400 mile round trip and the CEL is on. I got a code for the dpfe and when I opened the hood i discovered that it was burned in two on one of the vacuum hose connections. It's a black replacement one from autozone. Anyone have this happen before? It's less than 1 year old. Could it be an electrical problem since my gauges have started going crazy also? Still have the original so I'm putting that one back on for now.
