I know this is for the leak detection pump and could be a leak from a hose or the pump it self would the gas tank cap have anything to do with it?

I heard that this is a hard code to solve any advise guys I hate seeing that check engine light on lol

 

Start with the gas cap (maybe get a new one that seals better), then start check all hose connections.

 

Iv been planing on getting a new one because the ne I have has a key lock that is Jiged so I can put any keep in there turn it and unlock it ( I hate it) so ill start there

 

get the fancy locking gas cap that has a secret compartment that you can put stuff in. Like emergency gas money.....

 

probably the worse I dea iv ever heard lol are these real?

 

sorry but I have to bump this..

do I just start the engine up and feel the hoses for air coming out of them or what idk really

 

Would like a follow up on this, I have the same issue. Just came on Sunday. Not thrilled about putting in a new fuel pump.

 

Fear not Johnny9!

It's one of those difficult-easy things to do. Difficult to start troubleshooting due to not knowing where to begin. Easy to fix after you find the cause (as usual). I found a cracked tube which I then cut and spliced using a piece of fuel line tubing.

First things first. Clear the code then monitor for a repeat occurrence to confirm the issue is real. If real then, for many, the gas cap is a solution. Replace it and clear then monitor for codes again. It's a cheap simple place to start and is a good PM step even if it doesn't resolve the issue.

If the issue repeats then perform a thorough visual inspection, with gentle manipulation, of the hard plastic tubing that emanates from the purge unit (located under the Jeep, inside the drivers frame rail, approximately under the back seat). You may need to remove the shield in order to accomplish a thorough inspection so prepare the fasteners with penetrant (PB Blaster) the day before and remember to clear/monitor codes after repair because there may be more than one leak.

Good Luck.
