Sensor replacement is fairly easy. Just unscrews from manifold or pipe whichever one it is, and replace with new one. Not knowing the vehicle engine and emission specs, I found several brands and options on the car and would say $50-$80 for the sensor and 30 minutes or less to change it. Fixing them is not an option replacing is the only fix.
Note on a v-6 there are 2-4 of these on the car so you need to know which one is the problem. Codescan should help identify the culprit
