2011 Wrangler Check engine light ... have replaced gas cap…

2011 Wrangler Check engine...

2011 Wrangler Check engine light ... have replaced gas cap and tube to gas tank .. system checks good and runs for about 45-55 miles before light comes back on ... small emission/evap leak .... I'm frustrated!!

Mechanic's Assistant: Does the light stay on, or does it blink?

Stays on, thank God ... never flashes on/off

Mechanic's Assistant: Are you fixing your Wrangler yourself? What have you tried so far?

No ... took to my dealer.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

I'm thinkin' that will be enough for now ;-)

Hi,

Did the dealer do a smoke test to determine the filler tube and gas cap were bad?

Ask Your Own Jeep Question
Customer reply replied 4 months ago
I believe so ... wasn't there. Initially, replaced the gas cap 'cause it wasn't staying on/tight. Then the new one came off while driving .. they then changed the filler tube and all checked ok. 50 miles later light came on again ... after they reset the light there was no leak detected ... agh!! Thankfully, there was no charge for the last check as there was no defect noted .... is there a "sensor" failure as a possibility?
Customer reply replied 4 months ago
Ok Eric ... what next?

HI,

Yes, a common failure is the ESIM(EVAP System Integrity Monitor) switch which is integrated into the vapor canister. It is basically a leak detection switch that does a self check of the Evaporative system. It can set the leak fault code you are getting one of two ways - actually detecting a leak, or falsely detecting a leak.

As the last check showed no leaks, then the ESIM switch is setting a false positive and needs to be replaced

Eric, went out and did the ignition switch on/off three times test to see what the call out would be ... odometer didn't change, but the engine light flashed about 8 times and then went steady ....
Ok, that means that there is a code pending but has not set has an active hard code yet. It may take a few days before it sets as a hard code to retrieve it doing the key method
Ask Your Own Jeep Question
Customer reply replied 4 months ago
Should I take it to the dealer service dept tomorrow or wait for the code to harden?
Customer reply replied 4 months ago
As for the other item, is the ESIM switch changeable or do I have to change the cannister?
I would set an appointment for Wed. Or Thurs to give it a few days of driving to allow it to become a hard code
Ask Your Own Jeep Question
You have to replace the canister as the switch is integrated in it

Tks! Will try to get you feedback as this is taken care of by the local shop. Thanks again, Mike
Canister is around 150 and 0.6 hour, about 60, to replace

Eric, thanks for your help .. local Dodge garage did the work yesterday, and indeed the ESIM switch was faulty. Glad that is taken care of!! I do have one more question if I may ... I'd like to have an OEM remote start kit installed. P/N 82213625AC was the 2011 kit, and now has been discontinued ... the next generation/version (?) is listed as 82213625AD ... My question: Will the AD kit work in the 2011?? tks, Mike

Hi,

I show it only works on 2013 and newer, so it would not work

I did find the 82213625AC here
