So my 2015 Jeep EcoDiesel threw a CEL on my way back from folks this afternoon, about a 45 minute drive. Hot as Hades here in Central Texas today. Threw the code 5 mins after startup.
Ran the OBD-II scanner when I got home, saw it was P0420.
Just bought the truck in June, it had about 1/3 of DEF fluid in it. Dealer gave me two MOPAR 2.5g jugs of their DEF and I put in one, and put the other in the house to keep fresh. Now has just over 1,300+ miles on odometer.
Just had it in the local dealer for the TSB 18-022-15 REV. A & 21-045-15, but that code was not one of the specific codes listed. I've read the threads here about this code, but I thought it was more so limited to the MY 14 EcoDiesels?
I cleared the code with my scanner and will see if it comes back; any thought or suggestions? Thanks!
