Question about 2012 Hyundai Genesis 3.8 Sedan 3.8L V6 8-speed Automatic
Getting code po128
I did a quick Google search and found P0128 may indicate a stuck thermostat. The engine is not warming up properly. There are other causes: A code P0128 may mean that one or more of the following has happened:
* Low engine coolant level
* Leaking or stuck open thermostat
* Faulty cooling fan (running too much)
* Faulty coolant temperature (ECT) sensor
* Faulty intake air temperature (IAT) sensor
I got most this info from another thread on Fixya. I hope that it helps you.
