Trouble Code: P0EA7

[Goofy]

Hi folks,
since a couple of weeks have the following problem on my 2021 Wrangler with the V6 eTorque Engine.
I found out that the cooler fan starts running on low speed when the cooling system reaches a normal temperature (around 190°F) and switch to high speed (maybe 195° to 200°F).
This seems pretty normal to me but the fan doesn’t shut of o even change the speed if the temperature goes dow, the fan runs the whole time.
The Jeep dealer found the trouble code P0EA7 and told me they need to change the auxiliary water pump and did it last week.
On my way home I had the same issue so back to the dealer and the same code was present.
They told me that they now have to change the PCM which they have done yesterday.
Now I have a appointment next Thursday but I would like to be prepared because I couldn’t believe that the PCM would be the problem.
in my opinion it could be a temp sensor which gives wrong numbers to the PCM.
Did anybody had the ”same“ problem or trouble code and what was the issue for the code?

Thank you for reading and maybe helping me out. ,-)

Could be air in the system. I've had pressurized cooling systems in the past that have to be bled.

…great, they changed the PCM and now the check engine light comes on and the code P057B enjoyed the trouble code party. ?
