P0128 Range/Performance Problem In Thermostat
Everything is working as far a engine temp, cooling etc. What should I do or look for? Just did plugs, oil service, filters etc...
Thanks for your advice

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
use code scan tool clear the fault codes.
