please tell me the location on car of this item how to remove and replace part thanks code po449 on my scanner tool how about a picture no the purge valve i know where that is thanks

 

This should be covered under the 80,000 mile emission systems warranty.

 

yeah but my car is a 2006 does that still apply i have 65,000 mi

 

pretty sure the 80K on emissions is required by law.

 

I had the same problem a few months ago and ChevyMgr said its not covered. I believe the only emissions stuff covered is the catalytic converter and the PCM.

There is also a service bulletin on the P0449 code. Apparently a pin in the underhood fuse box can push out and kill the +5V to the valve, setting the code.

In my case, I unplugged the connector at the valve and the re-connected it and all is fine now.

The vent valve is on the evap canister under the car by the rear axle, between the spare tire well and the gas tank.

If you do need to replace the valve, it comes off easily.

Here is alink to the thread where the service bulletin is posted:

So i'ts not covered under the Chevy warranty?
ugh!

 

I believe that emissions warranty is as follows: Under the California Emissions Warranty, all emissions related parts are covered for 3 years or 50,000 miles, and a vehicle-specific list of more expensive emissions related parts is covered for 7 years or 70,000 miles. In addition, the 8 year or 80,000 mile coverage for the catalytic converter and engine control unit required by Federal law
also applies. So it appears you are out of luck. Of course newer cars with the 100,000 mile warranties are covered for any type of failure.

 

Hi all, I have a 2007 HHR with 16,000 miles and a code P0449 which I can't clear,I have replaced the gas cap and solonoid vent valve and checked the connector at the fuse box with no luck in fixing it, any suggestions?

 

Does anyone know a part number for this from like Rockauto or something? I picked one up from autozone and the power connectors are different....
