    I think it's E85 related. Have you been running that fuel?

    Air is pumped into the empty portion of the gas tank so the car can ensure pressure is being held, and there are no leaks. It's part of the EVAP emissions system. Look for loose hoses for the EVAP system, or a loose gas cap.

    Yes E50 was in the car at the time of the code. It has not re-appeared.

    Not sure what it means but I was getting that code over the weekend after hardwiring a radar detector.
    I checked all the fuses and found that I blew a fuse (in glove compartment, #17 i think) and after replacing the fuse the codes are now gone.

    I received the same code last month when I went on a trip. When I reached my destination I needed gas and the display said I had ~35 miles till empty. I stopped at a gas station and filled up and scan for codes while I was there. That's when I saw the code, I knew it triggered sometime during my trip since i scanned my car before I left. I cleared the code and it has not appeared again. Most likely I didn't tighten the gas tank when I filled up initially.

    Its an emissions thing. The DMTL pump is near the fuel tank that helps tank ventilation. It failed on me 4 years ago and dealer fixed it under warranty. Very common defect actually back then.
