It is not hard to change the sensor, it just screws into a threaded hole. The light will not go out immeditaly, after the sensor is replaced. It needs to go thru a drive cycle. Your best bet is to replace the sensor and get the code cleard by whoever scanned it for the 0031 code.

Often caused by a loose gas cap or fouled or failed air fuel O2 sensor. Check your gas cap is fully ratcheted, Drive a day or two. If lights don't clear you will need a code reader attached to the car to diagnose.

there are literally hundreds of codes that would turn on the check engine light. the track off and vsc lights come on together, indicating a problem with the traction control system. again, many different items will turn these lights on. the only way to narrow it down is to hook it up to an OBD-II diagnostic tool and find out all the codes that are listed. if you don't have one, take it to a shop
