I have a 2008 Santa Fe with the 2.7L engine. On that vehicle it's located between the throttle body intake (TBI) and the firewall. If you loosen the hose to the TBI and remove the top of the air filter assembly it is easy to see. The purge control valve is a pain to replace on the 2.7L, the electrical connector does want to unplug without some help from the bottom with a small screw driver. It's easy to disconnect the longer more exposed hose and remove it, but the short hose on the engine side is virtually impossible to get off without cutting it. You can't detach the purge valve from the rubber bracket without pushing it towards the passenger's side, and you can't do that with the hose attached. You can't remove the hose because of the 90 degree plastic elbow that is two inches long on one side and the bracket on the other side which gives you no room.
If you don't cut it you will spend hours trying to remove the assembly and fail. If you cut it the job will take 20 minutes. I suggest just cutting it, but be careful not to cut the plastic elbow, just the hose in small space where there is no plastic. The part number is 28910-3E100. I obtained the part from the local Hyundai dealer for less than forty dollars with tax. You can pay a lot more for it if you're not careful. The one from Hyundai did not come with the short replacement hose. I guess if you pay $90 you get the hose for free. Fortunately I had a few inches of 5/16 fuel line hose that matched the stock hose. It goes together easy, and it will save you about $200 if you do it yourself. I used an OBD II code reader to obtain the code (P0441) and also to clear the fault.
