Can it be heated with torch and placed in cold water to clean carbon build-up?

No, you cannot clean and 0/2 sensor and in this case, that isn't even your problem. The sensor appears to have a burned out heater inside and will have to be replaced. This is the upstream sensor on bank 1 which is the backside of the engine.
