I just got P3OFF and H2FDB. P3OFF I believe is boost leak which for some reason I get every once in a while when another code shows. But I got the half engine light , P3OFF and H2FDB. Anyone have any clue what H2FDB is for and what it means?

H2FDB - Short circuit or signal interruption

Not sure what it means... give Cobb a call before they shut down for the day.

I got a P30FF code with half engine light the other day... dont think you have a boost leak cuz I cleared mine and it hasn't came back.

I just talked to someone at COBB and they cant figure out what the H2FDB code really means. Obviously short circuit or signal interruption but thats pretty generic. So I had no luck with COBB knowing the code.

Well... I did a quick search and couldn't find much either. If I were you, I'd uninstall the Cobb, then connect the Cobb to your computer, make sure firmware is up to date, reload the maps, and then re-install. And see if you still get it.

Actually I did download the new version of the access manager, then hooked up the cobb ap and installed all new firmware. So it is now updated. But Im guessing your saying uninstall he cobb tune so that the new updates are in the tune?

By the way thanks for taking the time to search for me and see if you found anything. I tried the same with no luck. I was just out in the car getting on it pretty hard to see if it would reproduce the issue, but it didnt. So Im hoping its nothing serious.

Yeah i found one other report of this and it was also a one time occurance and never happened again... I think you'll be fine

Thank you. I hope everything is cool. It seems when you tune a car, theres a lot of different issues that could happen. I supposed to be getting a meth kit installed soon and get a pro tune but Im just not looking for anymore headaches. Just hoping everything goes well and the car runs good as its my daily driver. I plan on keeping it a while.

[skim7x]

Yeah I'm in the same boat... whenever you mod the car you are putting yourself at risk for potential complications... so I always make sure I have an extra little reservoir of money to deal with these complications As such, i'm holding off meth for a while now... need to save up more... right now my rims / suspension are giving me hell so I'm swapping rims / tires and it's costing me =/

Wow really? what kind of issues are you having with your suspension and wheels? I just got my wheels like a month ago and things are great. No rubbing and I have KW coilovers. My main issues were misfires and things associated with the tune. But I had the spark plugs replaced and a coil pack so no more misfires. But now I just have random issues like Ive stated in this thread. Ive had the dreaded P3OFF code a bunch of times. Boost leak, But have never found a leak. After the fitting to the FMIC were tightened I didnt get the boost leak code for a while. But now it returns. And everytime I get one of these codes I cant afford to take it in for some kind of checkup.

understand this is an old post, but I just read the same code H2FDB from my cobb. Could it be triggered by my low battery?

[davidwarren]

Hey- old thread, but I have the same H2FDB code on my cobb. I pulled codes because of a rough/stumbling start.

[Jklad]

I had this code also accompanied by p29f4 and 29f5, with occasional rough idle on cold start. Replaced lpfsensor, haven't gotten the codes since, but still rough cold start.

I think it means a light is out or something. I have that code and the warning lamp that looks like a lightbulb is on.

Pretty sure those are two different issues. I throw the H2FDB code pretty regularly and I don't have any lighting issues or warning lamps. I haven't figured out why it throws the code, but oh well, it runs great.
