Hi there,

I'm trying to get to the bottom a persistent P026C DTC that gets set every 2nd drive cycle in the winter. More details over here: (https://jeepgarage.org/f222/persistent-p026c-191738.html)

More reading has me suspecting a problem with one or more EGT (Exhaust Gas Temperature) sensors. I know a lot of people run TorquePro, DashCmd, or other OBD scanners on their EcoDiesels, and I don't have an idea of what EGT readings are "normal". Anyone want to share their values of these PIDs with me? Pretty please? :thumbsup: These are my values from a freeze frame:

Code:
OUT TEMP(°F)       32
COOLANT(°F)       178
ENG RUN(m:s)    08:24
CAT TEMP11(°F)    504 
EGT 11(°F)      725.9
EGT 12(°F)      514.4
 EGT 13(°F)      510.1
Thanks!

When my coolant is around that temperature, those other sensor temperatures look about normal. They vary from around 300F lightly loaded to 1100F during a regen or long heavy load.
