Thanks for this video. Would not have had a clue what to look for with the ESIM switch without this. Kept having a recurring "gas cap" warning and check engine light on a 2008 Chrysler Sebring. Changing rhe gas cap solved it for a couple of months before it came back. Went for a service at the dealer and they told me at was the ESIM switch, but wanted approx. $600 to change it. With this video, I was able to see what I was looking for, found the part for $35 and changed it myself. For anyone else with a 2008 Sebring, the charcoal canister is on the driver's side, and just inboard of the wheel well, so you don't need to remove either the wheel or the panel to get to it

Did this on a 2007 Jeep Liberty in about 20 minutes. It's located almost exactly in the middle and directly above the gas tank on the front side. I was able to get both hands up there to work without taking anything off. Super easy to work on (as are most things on this Jeep).

You hurried up the video at the most important times you might have struggled but it would have been nice to see the pressure needed and how it would come off and how it would go on

Would a 2012 300c have this in the same area ?

[davehardin]

where is the location shown on the video above? is it in a wheel well?

So, what's the deal that you didn't show how to reinstall the ESIM. It's not easy to reinstall this module.

I just did this job on my 2010 Ram 1500 with 25 gal tank. The video is good but here is extra color.

As was said in the other comments, the device is on the back side of the gas tank, on the drive shaft side. It is hidden by a heat shield. The tank does not need to be dropped at all as was stated in some other videos. Study this video and you can the feel around the device to unhook it in place. I did not need to jack up my truck at all. Remove that electrical connection by pinching it good. You will hear it click then you can pull backwards. Pulling the hose off requires some twisting to loosen it. Once that is done, wrap your hand around the device to feel for that tab on the bottom. Pull it toward the device and rotate the module. If you can do this, the reverse is easy. I did run my fingers over the gas tank to check for foreign debris before putting the new device on.

Last thing, the code will need to be cleared out. I did it by disconnecting the battery, then hitting the horn and cycling the ignition a couple of times. Got to get that residual voltage out. I did not do a full test of my truck but did an in place startup and the check engine light is off and the gas cap light is off too. I will drive it later today to test it further.

How long until your check engine light went off?

Where is this located on 2014 jeep patroit?

Can this be bench tested? On the self test, it couldn't stay closed to even run the test and failed for large leak. But can I energize it it see if it is closing? Is it 5v?

I replaced mine and now my gas gauge isn’t work. Does anyone know why?

[zeeman]

Is it the same location as challenger?

[beardsbucks]

I got a smell of gas bad after driving for awhile I have a 2005C coming from the evaporator tank so you think I need to replace the whole tank

[torrimalm]

Anyone know where it’s located at on a 2009 Dodge Avenger

[kevinb]

So a LDP is a ESIM as well does not make sense but who knows if order one for my RAM 1500 the CEL keep coming on so I hope this works for my truck

[tysonsmith]

I replaced mine light went off for a week then back on. Replaced it again light off for 3 days then back on 😢

[drxftaaa]

Where could it be on a 2007 Chrysler Sebring?

Nice vid, can u show how to take off the charcoal canister ? As it has 2 hoses w clamps nd may b few screws not sure ? But how do u get them hoses off the canister with out braking its clamps?

[AN-kgei]

Pardon me - just checked... Left rear wheelhouse area under splash sheild... I could have sworn it was front side of the tank in plain sight... I guess that changed.

Nice video. Any ideas where this part is located on a 2014 Dodge Durango? There is surprisingly very little online info. about this. I got the P0456 code indicating this.
