how many miles are on your car and have you ever changed the coolant and thermostat?

Welcome to the forum.

This code is often due to a stuck open thermostat.
Check the thermostat and make sure that you have the correct coolant additive.

P0128 - Insufficient coolant temperature for stable operation

• Insufficient coolant level
• Stuck open thermostat
• Faulty ECT


BTW. The temp sensor is at the thermostat housing - it is the sensor with the two terminals - the sensor with a single terminal is for the dashboard gauge.
Try the KiaTech web site for images showing the location.

For service info register (free) with KiaTechInfo and click on 'Shop' on the left, and for elect schematics click on 'ETM'.

Quality and not quantity counts.

I have a 2000 Sephia with a p0128 code also. I came to this thread for an answer to the question asked but only found more questions instead of a direct answer.

I have a new radiator, new water pump, new OEM thermostat which replaced another replacement thermostat that was 170 degrees, 10 degrees lower than the OEM thermostat and I still get the p0128 code (coolant temperature too low). If it's not the CTS, I don't know what it could be as the two other choices on the error code have already been fixed...I just want this stupid Check Engine Light to turn off and my car to not use so much darn gas.
So, I bought a new CTS but I'm not sure about how to replace it. I found where it is on the engine thanks to the pictures posted in this forum but I'm clueless as to how to remove it. It looks like you unplug the one end and then unscrew the other but that plug just doesn't want to budge. Is there something else I should use to remove the plug other than my hands? By the way, I'm a girl so maybe I'm not putting enough power behind the pull, or something. And yes, I know to wait to change it after the engine has completely cooled.
Thanks in advance,
