Replying to: b007halen (Sep 25, 2009 12:03 am) Check the gas cap, and also the hoses and canister behind the drivers side rear wheel. This is an evaporative emissions code, so something is wrong in the capture systems. Look for cracked or broken hoses, most are bigger than a vacuum line and smaller than a heater hose.

Replying to: jlflemmons (Oct 27, 2009 8:09 pm) I had a PO 410 code and my mechanic found a 30 amp fuse for the A.I.R. pump. He was going to replace the pump but after taking it out and testing it, it was okay. Since the new fuse was put in...the light hasn't come back on but it's only been 200 miles. Good luck with your 440 code.

Also, I signed up to GM Parts online just in case I need anything, I needed my VIN number to get the proper part - so I'm pricing the kit you mentioned just in case the fuse was not the entire problem. Thanks again
