if you have a code for a faulty o2 sensor the 1st thing to check for exhaust leaks before the O2 sensor as if this has been experiencing an exhaust leak then it will have been running very rich as the sensor will see the extra airpulled in as fresh / lean fuelling and be adding fuel to compensate.

The best way to find an exhaust leak is to run the engine from cold and feel around the exhaust joints with your bare hands - you'll have about 30 seconds before it all gets too hot and you should feel any escaping gas blowing over your fingers

if this is OK then check for damaged wiring and if thats OK, only then replace the sensor

Your answer is fine, just need to see the exhaust system and check the leak.
