I need help identifying what parts I need. All information online is for Yukon xl 1500 or other that do not match my 2004 Yukon xl 2500. After a trip into the mountains I got code p0449 and upon looking around I noticed something that appears to be mounted in the rear right behind back bumper area is completely missing. I have two hoses and wiring (two wires) hanging loose. Auto parts stores have been no help, telling me I need the part that goes up on the engine or other misinformation. Please see images and advise which part appears to be missing.

The smaller hose is the one I can find no information about. It was quite loud like the exhaust pipe and I placed the blue tape on the end just for vacuum purposes.

Good afternoon,

That is for the canister vent solenoid/valve.

I attached pictures of the part and the electrical connector for you. It is easy to reassemble. It just slides back into the bracket. If you are not sure, take it to a shop and they should be able to replace it in about half an hour.

Once this installed, the code will not come back.
