I have a 3.3L 2005 DGC. I noticed this vacuum hose is disconnected. First pic shows where it connects to the throttle, second pic shows the disconnected end. Where does the other end go?

The vacuum line that is shown connected to your throttle body runs to one side of the evap purge solenoid. A second line runs from the purge solenoid to your charcoal evap. cannister. If I'm wrong I'm sure someone will chime in.

Thank you, that's it. The lines coming from my evap purge solenoid were disconnected. Do you happen to know which hose goes to the top and which attaches to the bottom inlet?

As I recall the bottom line went to the evap cannister and the upper went to the throttle body. But if you really think about it.since the solenoid is normally closed when deenergized,the position of the lines shouldn't matter since the circuit of the fumes/vapor from cannister to throttle body would be exactly the same if the lines were reversed. Again, if I'm wrong and I don't think I am,somebody will comment I'm sure. Hope this helps!

Thank you. I connected them and I finally have no codes on this vehicle after a year of driving and 15000 miles.

That line was likely disconnected for the whole year I've owned the vehicle, I'm curious if it would have caused any damage?

You didn't change the intake gasket, did you?

And you got the codes mixed up. P0420 is bank 1 cat. P0455 is a large EVAP leak.

I have been experiencing emission codes myself off and on for the better part of a year now(p0440,p0456 and gascap warning appearing in odometer). I have attempted fixes ie: replaced gascap,new charcoal evap cannister,NVLD and codes persist.I feel like a cat chasing its tail! The **** of it is the car runs great ,handles great,brakes smoothly and cold ac(42-44 degrees) at 165,000 miles. Its just that darn yellow light coming on 1-2x/wk. The only recourse I have as I see it is to take it to the dealership for a1-2 hr diagnostic only and maybe do a smoke test if necessary. Tired of throwing $$ at what seems unsolvable. My avg. mileage is around 21 mpg which is about 50/50 highway/city driving. Good luck solving your codes..Lots of good information here researching for troubleshooting ideas using the search function.

Only part of the system you haven't replaced is the Purge Valve right by the air box (and the lines that connect everything). It's the #2 cause for those codes (gas cap is #1).
