You should list what scanner you are using to scan the X. The code that you listed is not a P-code so I'm assuming it is not a generic scanner. If the 02 sensors are working as designed per your live data then it must be something else. You said that the long term and short term fuel trim are ok. It would help if you listed the number for each.

Does your scanner do freeze frame? It would help to know what the engine was doing when the error light was set.
