Jeep Grand Cherokee SRT EVAP code P0456

The check engine light came back on the Jeep SRT. P0456 and P0400. In this video we replace the ESIM to attempt to fix the check engine light! Thanks for watching!

[@JoshShare]

Thanks for everyones support on the channel! Stay safe out there!

[@seanmaddox4274]

Hey Josh, do you happen to still have the part number for ESIM and seal?

[@kaykay209]

@joshshare I had the same issue.changed the purge valve and everything has been fine until this day.look into also.

[@Prins9205]

Thanks for this! It finally fixed the damn code I had for a while and would not go away.

[@user-wc5lq9xg1n]

Man, thank you so much. I bought a Jeep Grand Cherokee 2015 in the USA and brought it to my country for auction, but later moved to Germany, and here the prices for car repairs are very high. You saved me a lot of money. The work was not difficult for me as an engineer and took 5 minutes, but thanks to you I found the reason. I changed the spare part and forgot about it due to a mistake.

[@1SeanBond]

Impeccable Josh! Lol appreciate the way you explain it , excellent camera work & editing, we like your style! A Fantastic veiw✌ Be safe, Cheers 🍻

[@JoshShare]

Thanks!

I love this video! I had that P0456 code on my 2014 Jeep Grand Cherokee for months the first year I have to have my car CA smog checked. It was sometimes hard to put gas in my car without the gas pump cutting off as if my tank was full when it wasn't. I thought it was a major issue making me consider trading my car in to avoid the CA smog check, but I saw this video and followed everything you did including the moving back the fender lining instead of taking a wheel and the entire liner off like some other videos. I replaced the ESIM exactly like your video showed and just to be careful I even replaced the vapor canister purge valve underneath the hood like another video showed. About $60 in parts and less than an hour of labor fixing my own car in my garage saved me so much money from trading my car or getting ripped off at a mechanic shop. I took my Jeep for a ride and put gas in it with no problems. Drove it for a few miles a couple of times and then erased the error code with a cheap scan tool from Amazon, and perfect. No more error code, no check engine light and I can again use my remote start again, which the check engine light on prevented me from doing for months. Thanks!

[@JoshShare]

Im glad I could help!

[@lstruggy]

I’m about to do this and purge canister replacement soon for my 2007 jgc’s 455/456 codes just hit 213K miles! I’m confident that it’ll fix it if not evap lines will b next new sub cool vid fam!

[@faisalchoudhury9111]

Awesome video - what’s the scan tool you use to get the code on the SRT? I’m a new owner of a grand Cherokee. I feel like it’s a good investment 😂

[@lstruggy]

@@faisalchoudhury9111 Amazon had one ($50) got it for $22 on sale worth every penny! Oh and I did change my ESIM module attacked to the rear charcoal canister ($40) & purge valve canister ($25) under the hood both parts also got from Amazon. I inspected all the evap hoses w flashlight & codes are gone now took me 30 min tops to change both no more CEL! ❌💡❌

Great videos mate, just bought an ‘15 SRT so been checking your vids out, subbed 👍

[@JoshShare]

Congrats! Thanks for the support!

[@sgdluu]

I replaced the ESIM but it took 9 months for the computer to properly reset itself. I also had to replace the associated evap tube that refeeds the engine. Great video that worked with my Durango!

[@JoshShare]

Love to hear that!

[@jonh2408]

just fyi guys... you can reset (turn off) the check engine light by disconnecting the negative battery terminal for 60 seconds

[@christianblanchet6801]

Funny I just have p0440 and I am glad I found your video good job

[@user-bb4jv8ku9k]

Thank you for putting this together! Saved me the labor money! Just an FYI don’t take off all the clips just the 1 screw and the 2 clips. The side ones are a pain to put back on once they’re off

[@JoshShare]

Glad I could help!

[@JoshPutnam1]

Oh man, I just got this code this evening. Cleared the code, will check back if I do the repair.

[@kpenn5513]

CO local here. I just bought a 2014 Jeep SRT w/ under a 100k miles. Previous owner kept a good maintenance history. Look-like your about to switch things up. Appreciate you sharing your knowledge! Look forward to your future videos - Subscribed now!

You should also check the evap line under hood to purge it tends to crack

[@danieltopeteleon8179]

My 2015 has the same code. Will look into this to see if it works for me. Thanks Josh!

[@JoshShare]

No problem! Thanks for watching!

[@michaeltorres1889]

Did you try it? My 15 has it too

[@afocused2010]

Hello, my 2015 Laredo code shows same code (PO456). Should this be covered under extended warranty? Is it okay to drive jeep until I get this fixed?

[@steven8614]

Great video, thank you!

[@JoshShare]

Your welcome!

Fixed the PO456 on my 18 Durango. Light went off when I filled the tank. Thanks!

Hell yeah!

[@davidrogers3121]

great showing

[@JoshShare]

Thanks!

[@kenwilson4214]

To make make sure the replacement when you shake it will hear the solenoid...when its defective you will not hear it. Also the replacement oring is different than the oem.

[@franckbosson2726]

I fixed mine by just replacing the seal around the ESIM and using a clamp for the hose.

[@MaddJakd]

Seriously, that hose doesn't look tight at all. Thinking of finding a clamp myself. Wouldn't be surprised if that hose itself is the issue really

[@Davidcataneo1002]

Thanks bro ,I did it it and it worked

[@meekrodriguez6438]

I like your videos

[@MrMiike83]

Im suprised that they don't actually use a clamp to fix the hose back to the unit..great video

Great vid, where did you get the O ring from?

[@MSit-st7ph]

Thanks you - good job !

[@JoshShare]

Happy to help!

[@jasonbarnes2636]

Had the P0456 that went away but P0440 became permanent. Now will replace the ESIM and hope it fixes everything. Smoke machine didn’t leak anywhere but will test it again once the wheel well is opened.

[@marinanunez7507]

Do you need to open the fuel door to replace the ESIM? My '18 GC recently was at the dealership for this. I went to put gas in today and my fuel door doesn't always latch now. I see in the video your fuel door is popped. Just wondering if the dealership damaged my fuel door...

[@Bststv]

Thanks for the video, do you have the part number for the o ring?

[@nickv912]

Thanks Josh! Just curious, after replacing the ESIM do we have to manually clear the code or will the Jeep's self-diagnostic clear the code if the ESIM is in fact the problem? Appreciate the help.

[@JoshShare]

You’ll have to clear it with a code reader.

[@4wheeldriverican]

Great video awesome info.. did the check engine light come back on again?

[@JoshShare]

Thanks! No the ESIM fixed my problem

[@itsme2369]

Update ? Did it work ? I have the p0457 code on my 09 Cherokee

[@santiagodavila1426]

Grey video. I have a 2018. How did you know the ESIM was bad.? Instead of a hose or something else.?

[@graememiller3350]

I was the 300th like on this video!

Good video Josh. Hope that fixes your issue. I know I've shot from the hip plenty of times while fixing things on my vehicles haha

[@JoshShare]

Hahaha we’ll see what happens

[@ktsanf]

Josh, great video. Just did this on my 2016 Grand Cherokee Limited. Hopefully the code does not pop up again.....

[@bobby5digital]

Hey Kirk, just wondering if that solved the problem and the code went off for good. my check engine light just came on yesterday for this issue. Thanks!

[@ktsanf]

@@bobby5digital Hey Bobby - no more light since I did this, so all good.....so far....

[@alexanderliverano3257]

Did you clear the code or did it clear on its own?

[@ktsanf]

@@alexanderliverano3257 I cleared the code and it has yet to reappear. Thanks.

[@JoshShare]

It hasn’t come back since 👍🏼

[@ManuelRivera-np2ei]

Can I clear the check engine code with code reader device they have at autozone? I followed your video to swap out the part but I need to clear the check engine light.

[@Batman-bp9ui]

excuses me sir but i have a question What causes the Transfer case module to be bad ?

[@davidvail1996]

How do i go about safely clearing the codes? Do i leave the car running? Or how do i read the codes without starting the Jeep

[@Docblogs]

So did it fixes the problem??

[@mopar1590]

A did the check engine light go away after a week?

[@allisgood4536]

I guess that the bottle of Jack Daniels on your tool bench is for the times when the code comes back.

[@JoshShare]

Lol I’m glad it didn’t! The Jack is long gone haha

[@jasonbarnes2636]

How do you know if it was the rear ESIM is the problem?

[@deeznut5360]

What code reader did you use to reset the code?

[@Ken_Leivonen]

Did you replace the missing boot on the inside of the fuel filler door?

[@JoshShare]

Not yet. That will be next if the ESIM doesn’t fix the problem

Hey hope all is well, having the same issue with that code I replaced esim and o ring and did a smoke test but after three days it came back

[@fedwardsiv]

Did you ever solve the problem?

[@TheRWD82]

Hello, thank you for the updates, I changed the ESIM OEM for $70, after a week the check engine poped up again, and I had to change the vaccum harness too because it has some cracks. Maybe both of them needed to be changed. Anyhow, check the vaccum harness for cracks.

[@JoshShare]

Hopefully the ESIM fixes it. If not I’ll be looking into on there possibilities 👍🏼

[@ajuber876]

How did you test the ESIM harness to know it was bad...check for resistance or voltage?

[@michaeltorres1889]

What vacuum harness are you talking about?

[@skmg2888]

Whats the vacuum harness?

[@gol10dr45]

Normally it's the hose cracked by the intake manifold that is the problem with Jeeps.

[@alfonso7747]

Hey bro did this fix your problem? Literally did the same exact thing to my 14 but light keeps coming back on. Thinking it's the filler neck?

[@JoshShare]

The light hasn’t come back yet. Fingers crossed and knocking on wood

[@1972mdc]

Did my sister in laws as well - light came back after 600 miles...she had it scanned at autozone and had the same messages. They mentioned a second part but no details on what or where it is

[@MSor1203]

I changed that part. For me, it was not the issue. Still getting P0456 and P0455.

[@niceshopmxmx7161]

same to me i used a smog machine and the charcoal filter is leaking smog did you fix it?

[@MSor1203]

I replaced the filters but for me it did not fix the issue. Several months later I decided to replace the gas cap and sure enough that was the problem. Since then, I haven’t had those codes pop up again and it’s been a couple years.

Hey Josh...great vidoes...I have a quick question...have you ever had issues with an OBDII scanner, scanning codes on your srt? I have tried a couple scanners and none seem to work on reading the codes....any idea?

[@JoshShare]

I believe the OBD port is powered off the cigarette lighter/power outlet fuse. Should be a 5 amp fuse. A quick check is to plug some kind of accessory into the outlet to see if it has power. I don’t remember off the top of my head where they are though. I’d check in front of the shifter and inside the center console first

[@dicha-ni8ig]

@@JoshShare I checked the outlets...both...the one in front of shifter and inside the armrest and both work fine but the obd2 reader still doesn't read...me and my neighbor are stumped on this...

[@JoshShare]

What year is yours? If you look up terminal 16 on the OBD port that should be power from the fuse. Either a DVOM or a test light with the key in the “on” position

[@dicha-ni8ig]

@@JoshShare Will try that out...thank you...I have a 2015 SRT...also...did that new ESIM in this video take care of your CEL..?

[@JoshShare]

So far it has so I’d say it’s fixed. The light came back within days of clearing the light before I replaced the ESIM and it hasn’t come back on since

Interesting.... Every time it gets cold, I get the P0456 code, and this is the source? Honestly if that's where the leak is, that hose connected to it doesn't exactly seem all that tight but idk. Will have to look at this because it's emissions time 🙄
