I have a 2015 Jeep Ecodiesel I've had new since 10/16. Just under 25000 miles. Had my first CEL in January. It was P2BA9 (bad def detected). It was -25f that week, and I was making small trips. It cleared up on it own.

Today I was about 55 miles from home and P20EE came in, then shortly after a stop at the store P1288 came in. Does anyone have any insight into these codes?

Getting a new DEF injector. Asked the service writer if the 3/4 and 1 tons are having the same emission system issues or is it just an Ecodiesel problem. He said, "yes, most people with 3/4 and 1 tons are going to 75-80k miles then doing a DEF system delete. Then we never see them again because they have no more issues."

there was an SCr recall ?? When ? I’m dealing with codes
P20EE
P2002
P1288
P2b49

nothing is covered under any recall in CANADA.

my issues started when I got low on def fluid and refilled with same brand I’ve used for 9 years from the same store. After about 30 or so miles I got an incorrect def light. Hooked it up to a snap on solus + and found those 4 codes. Clear the codes. After about 100kms my truck tries to do a def regen and trips the xxxKms before limp mode light. So I do a forced regen on my driveway with solus+ clear codes. Engine light went off but still showing limp mode warning. so I reconnect solus + and it’s only showing the p1288 wsrning, which is an NOX sensor

Other then you guys having the SCR replaced, did you guys need NOX sensors as well ?
