2000 S40 Code P0128 (Coolant thermostat - coolant temp too low) S40 2000

Thank you! How did you detect that thermostat was bad, not a CHT sensor?
Did you take it to a dealer?
Did they try to clear the code first and it kept coming back? Was it expensive?
Sorry for asking so many questions, this is because of my experience with the dealer shop: they are so fast to replace things as the only option...
Is there a way to get to the route cause of this CEL code before taking car to the repair shop?
Thanks
