I have a 2014 Jeep Grand Cherokee Overland diesel. The check engine light came on and the dealer is too busy to look at it for a few days. Does any one know what the code P2000 means?
Well, the dealer applied the TSB and said that should fix the problem. Two days later and the same P2000 code reappeared. I guess its back to the dealer. In total I've been to the dealer for repairs about five or six times in the past seven months for two problems.
My Jeep was in the shop for five days. Hopefully the check engine light is gone for good. The problem was crystals in the dosing injector. They replaced the injector and the DEF fluid. I filled up the DEF when I purchased the car in November. I guess I won't risk filling it to the top anymore. It seems safer to let it run low and then only fill it up to around 40%. That should last me around six months.
My sister has a 14 Eco and her check engine light just came on. Code P20EE. "Nitrogen in catalyst in bank 1 is below threshold." Same problem with the dealer pushing her appointment out a week.
Has there been any resolution on this trouble code? I did find the following TSB on WK2jeeps.com:
Many of us are going through it now (including myself) and in most cases end up with a replacement CAT. Please note that the CAT is a new, redesigned, CAT. For more reading head over to the DEF problems thread in the EcoDiesel forums.
I have just recently experienced the P20EE on my 2014 jeep Overland. They replaced the cat on it and it drives very well now. The dealer didn't mess around because they saw it before on another.
