P0128 code tripping

[wattsl2311]

I have a 2012 Jeep Wrangler Unlimited Sport...I got the P0128 code and we did the following:
Replaced the thermostat, replaced the coolant temperature sensor and drained and refilled the radiator. I am still getting the code after I did all of this the next day. Any other ideas as to why it keeps tripping????

wrong temp t-stat maybe?

What did you figure out in that? I had the code pop up a few days ago. Cleared it. Came back today. Mopar tstat housing is on national back order. Looking for a suitable replacement

What year and model?

Could be a few things. Easiest would be to-check the temp sensor is operating correctly and the resistance changes as the engine warms.
Check relays and fuses. Be sure the fan is not stuck on. Or if equipped the flow regulator to the heater is not open.
Ut year and model will get you more specific answers.

Looks like thermo and housing are one unit…

Use correct coolant. Do not mix or bad stuff can happen.
