Getting message?:"Tighten Gas Cap" or are you Unable to fill your tank? ! Look here !

[ESV_Platinum]

I'm getting error codes p0449 p0455 on my 2004 Escalade ESV

I'm going to replace the evap solenoid with part number AC DELCO 214-2149

Is this part all I need?

Do I need any other associated parts? tubes?

Great write up Anthony, man i've been having this issue for the past 4-5 months and two dealerships couldn't figure this out.. I will soon buy this part and do it myself. thanks man, it takes me nearly 10 MIN to refuel the truck hopefully this will resolve my issue.

Thank you so much for posting this! We had the same problem, Tighten Fuel Cap kept popping up then engine light came on. We replaced the Fuel cap and it didn't fix the problem, then it started not letting us fill up the gas tank, so we replaced the CANISTER PURGE SOLENOID VALVE ($35) and took the tahoe to the gas station and the tank filled right up! We just changed it today so the check engine light is still on but it should be going off in a few days. Thanks again!

I have been getting the P0449 code as well on my 2006 Sierra...I just ordered this part from Rock Auto for $20 shipped...crazy that for the updated part for my truck the dealer wants like $150 (solenoid and relocation kit) and wouldn't sell me the part shown above...hopefully this fixes my issue

I ordered that part a while ago and replaced it on my truck. Unfortunately it has not fixed my problem. Is there anything in the engine bay like a solenoid or valve that could be causing this? I've tried to not pay a hefty fee for a dealership to fix this but I need inspection soon....
