I hope I could help you...
I just tagged Loyale 2.7 Turbo in this thread since that name was on the pictures I posted.. I don't know if it shows up for him or if I need to private message him to see this thread. I just joined the forum so still getting used to things.
Sorry for comin' late to the party, but I've been in "
offline mode" since some time ago, and being pretty busy + tired nowadays... However, I hope to answer your Questions, properly, as far as I could, doin' my Best effort for helping you and others who might find these posts, useful.
... My ecu says my temp is at 190-200 degrees depending on how hot it is and if my ac is on, but my factory dashboard guage reads about 1/4 up the guage from cold 100% of the time. It never moves at all. Can anyone help with this? ...
I assume it moves to zero when the key is off, and only rises up to
¼ when the engine is Running, isn't it
? ... otherwise the Gauge at the instrument cluster, is Damaged and needs replacement.
... The sensor seems like it is working according to the ecu. When the car is cold the ecu says 80-100 degrees. After it warms up 190-200 degrees. And it seems to climb normally while warming up. My sephia has only the one plug on the thermostat housing ...
I
assume that those readings were taken with an OBD-II Scanner, isn't it
?
If so, they're accurate, and the
¼ reading at the Temperature
gauge is the problem.
In some cases, such fail is related to the
P-0128 "Phantom" code.
You can either try with another instrument cluster from a Junk Yard to see if the readings goes back to normal on the instrument cluster's gauge, and / or trace the wirings, looking for a loose / corroded connection on them.
On that second option,
I bet that your Sephia's instrument Cluster, has loose its connecting screws, if so, the
Solution to your Sephia's problem, is as simple and easy, as just taking off the instrument cluster for cleansing its electrical contacts, and
retighten all the Screws behind it; because said screws are the ones who sends the electrical contact to the Gauges.
You can see an example about how those contacting screws works and also how if they are loose, they're the reason for some fails on the gauge's readings at the instrument clusters, Here:

Does anyone know where to find a factory service manual? ...
Once upon a time, Kia offered all that information at the "
Kia Tech info" website, by free... it is also known as KGIS, but such great site, suddenly became a pay per read website, and somehow, they
banned all the online sources of information, such as scanned copies of factory manuals, due to copyright infringements, you know...
That website still exists and holds that info, but you have to
pay in order to gain access:
