Codes on S40 S40-V40

My S40 check engine light recently came on. I checked for codes and have a P0128 and a P0130. 128 is thermostat, 130 02 sensor. Car runs no different than before the check engine light went on and also gets the same gas mileage. I think I will check hoses for vacuum leaks for the 130 code first, and change out thermostat also. Anything else I should check?

What year is the S40? How many miles on the car?

Keeping it running is better than buying new
