Yes, the adaptive values can be reset with Autologic.The engine ecu will then be able to get the oxygen sensors cycling for proper closed loop operation.As I said they are very fussy,so it should be OK after that.There is always a chance that there is a physical problem with the Can pair but its very unlikely - in diagnostics you can NEVER say never... But being that the fault only flags when you get to 3000rpm it follows that its most likely a lack of message being put out on the can - bearing in mind the can is active as soon as the ecu's boot up and are pretty much constantly sending messages back and forth.
The other point I would make is that its all very well quoting P codes and their meaning,but in the diagnostic world they are only used as a guide - the ecu's can only report something they don't like using the nearest code they see as being correct.Often its miles from the actual cause and can only be taken with a pinch of salt.The main thing is that if it returns after noting and clearing is that whatever the fault is - it is clearly a current,not historic fault.Then you have to think a little further out of the loop as to the ACTUAL cause,rather than just relying on the written list.
