Code P20EE just popped up on me on my drive home today. I searched the forum and did not find anything on it. Has anyone else experienced this code yet? I have just under 8000 miles on the Jeep right now and this will be the 3rd trip to the dealer now.

Thanks for any help.

P20EE = SCR NOx catalyst efficiency below threshold bank 1

SCR = selective catalytic reduction

Have your dealer look at this asap before you go into limp mode. I believe there' a TSB on this.

I got that a couple of months back, when mine had about 3,000 miles on it. The dealer inspected, found nothing wrong, then reset it. That's the only time mine has needed a dealer visit. I'm currently at 5,200 miles, I don't drive it a lot.

Yeah, it was a little odd.

Trigger and nookie, what happened with your P20EE codes? I got it today and would like to know what action the service guys should do.

They flushed my def tank and ran a Regen..... I got it back and the code came back within 100 miles. They are now waiting on some special tools to diagnose it yet they can't tell me what these tools are. So at the moment I'm driving it around with a cel on.

I kind of feel bad for highjacking this thread since it is in the export section. Oh well. I took my vehicle in for service this morning. We will see what they say about my P20EE code.

EDIT: The service manager called and said that the problem is probably the catalytic converter (as expected). They have ordered parts and hope to have them in a couple days.

Update. Now the service manager says that they have a DEF injector on order and it is in back order status. He does not know when he will get it. So, they are not replacing any cat' part.
 
#11 ·
Figures. Maybe I can keep the DEF injector they take off......
It does appear that catalytic converter is the fix. But, I guess they need to replace parts in the order they think is correct.
 
#12 ·
Update on mine!!. Replaced the Catalytic converter on it today, new & shiny., even smells like it's being broken in.
Just about 1 year to the date I've been driving around with P20EE/DEF messages. hopefully this is the end of it!.:cool:

Had 2 recalls done @ same time, dealer has been excellent help through all of this. will keep you posted.
 
#13 ·
Update on mine as well: just got it back from the dealership yesterday, this is at least the third time they've inspected the P20EE triggering my check engine light. Like nookie's they replaced the catalytic converter on mine too.

Hopefully this is (FINALLY) resolved...?
 
#14 ·
It's not resolved. The MIL came on today, 80 miles after getting the JGC back from the service department. I'll bring it in on Monday to see if it is P20EE. I'm guessing it is.

Is there a way I can read what the error code is by myself? Or do I need to buy some kind of reader to connect to the JGC?
 
#17 ·
I had the MIL come on on Friday as I drove home, didn't know what it was but it still drove as usual so I kept going. Drove to a couple of places on Friday night then on Saturday the MIL was out. The OBDII Bluetooth adapter arrived today and I too have P20EE. So I will be heading to the dealer tomorrow. Just about spot on 19000 miles when it came on. I didn't clear the code.
 
#18 ·
Another Friday and another MIL. I mentioned it to the dealer when we were talking about something else and he just said "Oh yes, these have been having some cat problems, make sure you mention it at the next service." Which means any day now, so it wasn't going to be a significant wait.
 
#19 ·
At the last service they reset the code and said run it for 60 miles and see if it comes back on. Well not for 10 days, which for me was 700 miles. But now it has settled in to stay. I emailed them a screen shot of the code reader and then dropped in because I was nearby. They told me this is common, some are going in 5,000 miles. They say they are getting crystals forming in the DEF and taking out the injector. They ordered a new cat but told me they are on back order. There's a new radio on order too, so they can take it for both at once.

They said there is a long validation sequence before they can replace the cat, but that if I didn't need it in the end there were five or six others who would, so they ordered it anyway.

I tried to say "well at least most people don't see this" and they said "wellll... maybe more are than aren't". There was nobody waiting so we had a little talk about the poor design of the diesel installation, they mentioned the weak and exposed DEF injector and suggested I check out the dom42 plate. I told them I'd already got it but was waiting for them to fit the rock rails (now done) before I crawled under and bolted it on.

I hate to say it, but this is sounding like a product that wasn't ready for customer release. If they can't make a cat for these that lasts 10 years or 100,000 miles then they are going to get a lot of lemon law action. Sadly this is the sort of thing that keeps the class action lawyers happy. Hell, they've sued for harsh shifting transmissions before.

2014 JGC Overland eco-D purchased July '14, now in shop for 4th time for P20EE - replacing Cat and O2 - parts on order now going on 3rd week at dealer, don't expect parts arrive for another 5 days, so will be out of service for at least 3 weeks and 4 visits. Dealer svc manager insists this will fix, but I am skeptical at this point, but having seen others post that the cat fixes it I hope so.

Service newbie for this code. It has been cycling on/off for 2 months and I've been trying to arrange to bring the truck in; I finally scheduled an appointment this week. Dealer promised to put me in a rental. I'll let them do their thing and reflash but if that doesn't work, I'll be adamant about ordering me another CAT. Unless I missed something, that appears to be the only solutions.

It's not that I'm slack but I've been to the dealer twice and each time they didn't have the diesel tech working. Apparently that person works 7-5 M-F; I might need to change careers....

Took my truck in and got it out same day after they flashed the ECM. Drove home then next day the SES light came on again. Oh well, service guy said it was 50/50 chance the flash would work. Said I'd have to play the game and bring it in again so they could run it through the process to order another cat.

I will say the flash did something to the shifting as it feels snapper between shifts.

Does anyone have the address for Jeep to send a complaint? With all the problems I'm seeing, I want to get in front of this thing from a Lemon Law standpoint. The TN law which applies to me stipulates:

It shall be the responsibility of the consumer, or the representative of the consumer, prior to proceeding under the provisions of 55-24-203, to give written notification by certified mail directly to the manufacturer of the need for the correction or repair of the nonconformity. If the address of the manufacturer is not readily available to the consumer in the owner’s manual or manufacturer’s warranty received by the consumer at the time of purchase of the motor vehicle, such written notification shall be mailed to an authorized dealer. The authorized dealer shall upon receipt forward such notification to the manufacturer. If, at the time such notice is given, either of the conditions set forth in subsection (a) already exists, the manufacturer shall be given an additional opportunity after receipt of the notification, not to exceed ten (10) days, to correct or repair the nonconformity.

So everyone with this problem needs to call (877)426-5337 (Jeep Satisfaction Hotline) and report to to Jeep that this is an occurring issue that needs to be resolved so they make this a recall. I had my CAT replaced at 17,000 miles and I just got the same code at 23,000 miles. Issue is not resolved. It is in the shop today... The more people that call the sooner we have our Jeeps back.

I've just joined the P20EE club :(

Bringing our Travel Trailer home from the storage yard, up pops the SES light!
Checked the code with my Torque app and Tada! there it was....

Called the dealer and spoke with the service writer and explained the code but he said they would have to do it themselves to ensure they got the correct parts. The bad news was that the first appointment was a week from tomorrow....I then called Jeep to ensure they had the Cat converters in stock and also if I should drive our Overland while it is throwing the code. He said he would check with engineering and get back to me within 24hrs. At this point, after 23k miles, I will take nothing less than a replacement cat. They asked if I could take it to another dealer but we live in a small town in Texas, so not much joy with that!

This really effed up our travel plans for the next 3 weeks as the Jeep is our only tow vehicle.

Another issue also reared its ugly head.....pulsing from the front brakes!
Just in case it was a pad material issue, I went on I-10 and did a couple of hard 60-5mph stops but even after that I'm still getting the pulsing. You can feel it at low speeds but it is definitely worse from around 50mph and up, as it shakes quite badly.

So, I hope the dealer can get both these issues sorted. Our Overland has been just great for 23k miles and now these things occur. Not happy, but not ready to go postal quite yet :lol:!

An appointment plus a week later to bring your vehicle in when it's throwing an emission code? That's baloney. I had good luck negotiating a rental while my truck was in for that repair and I think you would have a good case after making you wait. Your throbbing brakes sound like warped rotors. Pads are not a warranty item, but rotors darn sure are after 23k mi. Negotiate a rental for P20EE and then mention in passing could they also check the brakes.
 
#31 ·
I didn't get rental car coverage and waiting for FCA to reimburse me for the expense when I brought mine in for P20EE repair. The dealer was fantastic in getting it done in 48 hours.

Pulsing brakes almost always is warped rotors on these. The WKs were known for undersized brakes and warping especially if you towed small trailers w/o brakes. There was a Stillen rotor / pad upgrade for the WKs that I did and the brakes were perfect after that even when towing 6k lbs (with trailer brakes of course).

As for calling customer service - I tweet it to @chryslercares as it's a public feed and they get back to you much faster than waiting forever on the phone.
