Thermostat or Temp Sensor or Both

I have a 98 S70 T-5 and have a little problem. Coming home from a 60 mile trip my check engine light went on (imagine that). I knew something was wrong because my temp gauge was reading at the 1/4 mark. I took the car into the shop and got a code of 123-coolant. The Volvo mechanic reset the light and said if it came back on that the temp sensor needed to be replaced. Well the check engine light came back on as my temp gauge never went past the 1/4 mark. I find it curious that the light went on because just last week I flushed my coolant system....

My questions: Is the thermostat the same as a temp sensor or are they two different parts? How easy are they to replace (is it a do it yourself job) and if its a thermostat what temp setting should I buy?

Comments are appreciated.

Thanks.
