I'm new to this forum, and am having problems getting my car inspected. I went to the GM dealership to get my 2007 Chevy Impala LS check engine light diagnosed, and the codes that came up were P2440 and P0411. The dealership told me my car was no longer under the power train warranty for this specific problem, and wanted to charge me $598.00 for them to fix it. Does anyone know an easier/cheaper way to fix this? I'm not a huge car person so i can just buy the part or whatever i need and have my step father help me do it. But i cannot find anything on what to do anywhere. Thanks in advance for the help!

Any other information you guys might need to help , let me know.
Those are codes for the air pump system. Even if you are out of the power train warranty, someone correct me if I'm wrong, but that should be covered by the emissions warranty.
See that's what i thought too. But the guy at GM told me i wasn't . I was wicked confused :-\. Now im just trying to figure out a better / cheaper way to get it done so i can stop driving around with no inspection. ( Still got the 29 Days though to get it fixed )
Or tell the current dealer it should be covered under the emissions warranty. When my cat was plugged, it was like pulling teeth to get the dealer to replace it under the special policy adjustment. I had to provide them the reference number for the warranty extension to get them to do it for free...
Call me cynical, but I think the service departments see if they can get a sucker to pay for repairs that should otherwise be covered...
Protip: If you don't know what you're doing, don't do it.
That's why I recommend calling another place, even if it is further. You can get the information from them and then go back and say look here is how it is (if the other place is further and you don't wish to travel)
A bad air pump shouldn't have a significant effect on gas mileage. It's one and only purpose is to inject air into the pre-cat exhaust stream on start-up. All it does is heat up the cat/O2 sensors faster.
P02440 is likely causing P0411, I would check the solenoid valve first and make sure the vac lines are all good. The dealer wanted $80 for the valve when mine went, I would expect it to be around the same price for the '07
