Code 2A17 = Failing DMTL pump?

Scanned with BT tool and got this code. Does this code mean it ran diagnostics or it ran it and the pump failed the test? I get no SES or CEL.

BTW: I also did a Google search.

Update: I erased the code and plugged back the wire that disables the exhaust valve (like the golf tee mod) and code never came back.

They have been known to fail too. If it comes back, take to dealer.

What do I say to the dealer? I scanned it with BT tool and saw this code? LOL

Or I say something like "I don't notice the whiny sound in the trunk after I turn off the car anymore"?

I get that code every so often and its when fueling my car....Happens when the gas doesn't fill up and the gas nozzle keeps clicking off and I would have to press it only half way to fill the car....As soon as this happens I get that code...I clear the code and my next gas fill up is normal...Not sure if its related to anything with the exhaust flap like the OP stated

The exact same thing happened to me two days ago!

Was your car on during fill up or did U get the code when U started the car?

Just a few months ago started having random problems with fill ups. Thought it was the gas pump causing the problem. There was never a CEL associated w/ the fill ups. Ran a BT scan today & got a 2A17 that was old, but never got a warning light..

Car is never on when I refill...It just sometimes acts funny for some reason that when I press the gas button it will not allow it to be fully pressed and I have to baby the gas into the car....This only happened to me like 4 or 5 times and each time I get this code...I clear it and then its normal on the next fill up....I dont worry about it at all and I think you shouldnt either....These cars have alot of electronic gremlins that act up and set of a code for no apparent reason...It was so much simpler back then with the older cars!! lol

Sorry to bump this old thread but the same thing happened to me. I just BT scanned my car and got the 2A17 DMTL pump failure code. Few days ago, I tried to fill up the tank, and the nozzle could not be pressed fully and kept clicking like you said.

One member took out the DMTL pump and used an air compressor to clean it out and it fixed it for him. Apparently it's very easy to access (like 30 minutes with a jack) and in the left rear bottom of the car behind a plastic panel. I'll try to clear the code, refill gas, and BT scan again. Hopefully this will be useful info for future reference. This DMTL pump is another epic fail for our car.
