2004 Suzuki Verona Q&A

2004 Suzuki Verona Question: I continue to receive an engine code - P0128 with the check engine light.

I have replaced the radiator (new), replaced the Antifreeze with the green 50/50 mix and the radiator/thermostat temperature sensor. I am told that the fluid in the radiator is not warming up fast enough? How do I get the light to stay off? thanks -
