CEL is on and generated code P0449. I checked the wiring for the EVAP vent solenoid and it is getting power. The local dealer wants $170 for the solenoid. Advance Auto says $30 but they can't get it.

I've looked around a bit and can't find a part number for this solenoid. I have Alldata subscriptions for my cars, but this is a neighbor's car so I don't want to buy this subscription.

There are likely other issues I need to look at as well, so any advice on those greatly appreciated. But especially, if someone could help me identify a good part number, that would be great.

I found this pic on the web. Is this the right part? http://gsi.xw.gm.com/image_en_us/gif/000/000/010/10865.gif

Thanks in advance to all!

Think it looks more like this:

http://www.gmpartscenter.net/index.php?i=2&model=694&make=116&year=2008&section=2&catid=30153&type=parts&subcatid=32261&item_collision=1&items=none&image=GD04240&catid=30153

Check their price....about $104.....

This is assuming it is the vent solenoid that is the problem, and not a leak somewhere else or a bad pressure sensor....

Another thing.....check your emissions warranty....if you have California emissions, this part may be covered in the warranty(8years/80K, whichever first)....

Hi infj23. Here is a pdf you can download for trouble shooting the evap vent valve. Power to it doesn't mean ecu is controlling it. Ecu drives ground I believe on the canister valve.

Thanks Gus and nickb2. I haven't had a chance to work on this any further but I'll get to it eventually. Thanks for the guidance in the right direction.
