Have a read of this link as it relates to the eco diesel:
https://www.tsbsearch.com/Jeep/18-012-16
Page 5 para 10 refers to the exhaust gas temperature sender (part # 5146662AB, Walker part# 273-10332,

which is located at the DPF inlet (which may be related to your P0428 code) & how to clean/test the sensor
This link:
https://www.jeepgarage.org/threads/code-p0428.99648/
also refers to a similar problem & mentions DPF cleaning.
Cheers
