S.O.S. 44,000 miles later

See post #23. check engine light came on again after 44,000 miles. Now 88,000 on clock. Same codes. Same fix, replace purge valve sol.(chevy part) and gas cap for grins, Boom Boom out goes the light!!!!!(afer a few miles for the computer to sniff and reset... Maybe the ECM is programmed that way? Make you mad after 44,000.... Oh well easy fix, once again: Thanks to FORUM and Owners for all help!!!!

I joined this forum, just for this thread and it was well worth it. I had this error fixed the first time by the dealer and they poor job and charged me $260. This time I did it myself following instructions here and it took all of 15 minutes, and that's even with correcting the poor dealer work. I picked up the original part that came with my truck at Autozone. Just ask for a Duralast part number PV485, it should coast around $24.99.

That's good to hear, glad it helped you out and you got the issue resolved.

I had this code P0449 appear and after some web research i ended up here. I'm glad i did as it seems it will save me some money in the end.

But i do have a question. First, i have a 2009 Ext Cab Silverado. I have located the evap solenoid on my vehicle and it is the type with the two hoses coming off off it. One leading to front of vehicle to purge solenoid and the other to the filter next to gas tank. i have checked gas cap and it seems to be sealing well. I'm hoping to not spend a lot to fix this so i purchased the PV485 solenoid from Auto Zone which i believe is the design before my model year was redesigned. As you know this solenoid only has an inlet for 1 hose so i'm assuming i just attach the hose leading to the purge solenoid to my PV485 evap solenoid and cap off the hose which runs to the filter which i will just leave for now hoping this fix will last awhile.

Am i heading in the right direction with this?

With the PV485 you will not need the filter, so you are correct in thought process. The PV485 has an integral filter that's why you don't see two places for hoses. You're looking good.

This is correct. No remote filter= only one hose.

Welcome, stick around make some new friends

Will this application work on a 2007 Yukon XL? Is there a seperate process for that? I have just began to study the repair? Is there a website to get the repair buletins? Thank you.

It should be a very similar, if not exact, repair for an 07. I know there is a ton of replies in this thread but a lot of people have added to it and a Yukon may have been covered. Take some time and read through, hope it helps you.
