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.

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

Rick: Purchased the kit from a local dealer was $51.00 with tax. Had it put on by another shop who charged $100.00. I had a new AIR pump put on about two months prior and the engine light came back; so I purchased the part you suggested earlier. I put just over 175 miles so far and so far so good. The kit was much more extensive then I imagined. I was expecting a hose that would run up and out near the battery; It was much more then a hose. There were two separate electronic connects with two plugs each. I also had my gas tank cap replaced. The dealer suggessted doing that and it was under $30.00. Apparently the rubber seal on the old one was shot. I never thought to look there so I'd thought I mention it. Hope the light stays off. Thanks again!
#70 of 80 2001 GMC JIMMY.. Help ... Code CO265 ???
Mar 03, 2010 (7:43 am)
My 2001 GMC Jimmy 4X4 on demand, 4.3, SLS, 2 DR has both ABS & Brake lights on dash on intermittently ? The lights never come on when outside temperture is below 35 degrees? Also they may go off by shutting off & restarting engine? Local dealer replaced one bad bearing hub that was making noise but that did not correct the issue? Code they said they found CO265 ?
I mention to them my ebrake pedal failed to stay down and maybe it was emergency brake partially engaged? They said that would have nothing to do with it because emergency brake is mechanical and this is a differant issue? It was mentioned that maybe it is the ABS Central Control Unit....Big Bucks? Here is my question guys... Does anyone check anything out before just makeing statements? Is there no procedure to follow. Thanks for helping me out, I am a mechanic from the 50's..... Frank
