I scanned the vehicle and got P0128 and replaced the engine coolant temperature because it told me that was the only possible cause on my scanner and i read on here that this code can be caused by a themostat and i told the owner that owns this vehicle that it could be that but she told me that the heater works all the time. So what else can i try although that i cleared the code ?

P0128 = Coolant Temp Below Thermostat Regulating Temp.

Replace the thermostat...it's sticking open.
