P0340 code

![Question](https://themustangsource.com/forums/images/icons/icon5.gif)
Hey Guys,
I have a issue, When ever I turn on my Stereo system and the sub hit the car surges a tiny bit. It's really weired for a while I thought it was the road or something. I would turn down the stereo and its fine but as asoon as the Sub hits it happens. I got a light so I read it, Turned out to be P0340 code. I took out the C&L and tune to be in the safe side for warranty. Driving today after a 4 days of having the code it turns off, Since I have been with my girl for the weekend and stereo low. Have guys ever seen this? It's really weired

Well,
I had my battery die yesterday after sitting in the garage for a week and a half(first time failure). Went looking on some of the other forum's and found out a few things. Namely that the stock batteries arn't very good and may last only 2 1/2 to three years before they expire.But in your case there is a TSB 06-19-12 that states that a bad Alternator can be the source of DTC codes P0340 along with P0344.
Here is the PDF file. Hope this helps.

I didnt clear it. It cleared it self. I know it should go off within 3 key Cycles if it didnt pass the paremeters. I havent had to sound up so it turned off. I haveto have it up untill Sat hopefully comes back on. Thanks!
