Evap not ready... possible bad gas cap

[Deleted User 38384]

I did do enough checking, cleaning and eventually found with all my care with the cap, nothing could be done to tighten up the loose play within the mechanism. If it were not for new to used feel when clicking and o ring style, I would have thought it was a leak in the evap line. I'll dig up my old cap from the rubbish I plan to leave for pick up. Once I retrieve it, I'll post a picture of the o ring style from a 2019 cap. It's different than the 2022. Also thinking Mopar may have updated the gas cap sometime after 2019, knowing of evap issues. After all my original never stated to click 3 times... Only once.

Yeah I know with my old Camry fuel caps, once they went bad, no amount of oil or cleaning whatever fix them. You just had to buy a new one and pray it would work.

I'm lucky in the EcoDiesel that I have, even though they don't advertise it, it functions like a capless fuel tank. I know this for a fact when I drove a whole week without my fuel cap on and got zero codes.

I'm not sure if that's the same with the gassers, but it might be. It would be worthwhile to look at your filler neck. On the EcoDiesels, they have a plug type cover in the filler neck, which is why we have those specialty filler bypass things in the jack stand and bolts area. Not sure if the gassers have those fill up tubes as well. But if you need one of those to put additives into your fuel tank or to be able to get past the filler neck to add fuel from certain carriable containers, then there's a good chance your Wrangler is actually a non-advertised capless fuel system.

I know my wife's Subaru is just an open neck with a filter at the bottom, if I leave it's cap off for more than a minute it'll start bitching at me.

I think I have a thread about it here somewhere. Let me see if I can find it

Without going into the why, I've been driving for 20 mi now, two different trips without a diesel fuel cap on my Wrangler.

So yeah 20 miles in, and I've still not gotten any check engine light or codes thrown...

Has any of my fellow EcoDiesel owners ever gotten a code thrown for the fuel cap not being tight enough or loose?

I'm starting to get the feeling the cap is literally just there for debris protection.

Hope this helps you in some way!



On a side note, it just dawned on me what your name means.
Why not just spell it out normally?

It was to be on a all black Sport S from North Carolina licence plate. Tar heal baby jeep in condensed form. It got sold before I could make an offer, and I cannot figure a way to change it on this forum. I ended up getting my Jeep from Texas, so as what VA people say, it is what it is

One note... I have over 85K on the odo. Who knows how many times the original cap was removed and installed before I obtained my Jeep.

Ask the admin to change it, Sugarbooger
