The hose next the battery was my issue. For now I have just wrapped electrical tape around it.

 

I am having some similar issues. However, I have all the same symptoms as what most on this thread are having with one huge one that doesn't make sense. My jk will just shut down. Does anyone on here have any idea as to why and what my next right steps need to be. Thanks for any help or advice.

 

Also having this code. I just checked my hoses and nothing seems worn or cracked. The one by the battery doesn't touch my battery so seems in good shape. Was everyone able to clearly see they had wear and an issue when looking at the hoses?

 

Not sure what engine you're running, so I'll pretend that you've filled out your profile like you should in my answer and that you have a 3.8. On my 3.8 I wasn't able to see the hose until I pulled up the valve that is attached to the TIPM. It is a bent tube on the bottom of that valve that is a bit difficult to reach and, if slightly cracked, wouldn't be visible unless you pulled up the valve, rotate it as far as you could, then checked the bottom of that hose. If you're confident that you've checked the hose well, suggest checking the gas cap. You could clean up the seal seat for the cap and maybe put a little bit of silocone grease on the gas cap seal and massage it into the seal. Also check the lines at the evaporative canister to ensure that they are in good shape. Again, another issue that could be revealed in your profile had you filled it out: Has your evaporative canister been relocated? If so, double-check the seals--there is a rather delicate one that is notorious for getting mucked up when relocating the canister.

 

I solved mine yesterday(fingers crossed) flipped white piece over on relocated can and haven't had a CeL or gascap warning last 4 startups. FWIW I'm running a 2014 with the metalcloak relocation kit

 

Google brought me to this thread. I didnt fill out a profile because I use wranglerforum for most of my JK needs. Thanks for your passive aggressive response i'll take a look at that stuff if it pops back up.

 

Mine has been doing this same thing and I will now have to look up by the battery. If that is not the issue I will just get rubber hose and replace the junk factory plastic of tubing.

 

I found this hose (Stock Code 04627316AA
Transmission & Transfer Case > Case, Extension, Oil Pan, and Indicator (Dipstick)
Assemblies
Sensors, Vents And Quick Connectors) broken in half.

The other open hose I saw was from the relocated vacuum valve.

My code shows only every 5-6 months. Very frustrating. Where to go from here?

 

How did you resolve the issue? I am having the exact same issue 2012 JK Sport

 

I don't know about him but on my 2012 it turned out to be the leak detection pump on my Evan canister. It's that white box. Disconnect your battery and install. Clear the code after that and you should be good
