last night i was driving home from work and started to hear an exhaust leak,to-day i looked and found that there are two tubes that come off the EGR tube,one goes to the DPFE sensor under the EGR valve which only has one connection and the other tube has no hose on it,where does it go?

ANY HELP IS MUCH APPRECIATED............
thanx in advance.
