Yea.. Scorpion, did you check CA techinfo? 'cos I can't see this code in EU one. Also looks like a functional code rather than electrical. But again, we in EU do not have P010F on LS.
I would start by checking idle grams of air flow and do a rev sweep to see if the output voltage follows smoothly and doesn't skip around. Then swap them left to right to see if codes or data output follows the sensors, if something is wrong try cleaning them.
Very unlikely but you may have a harness issue, that's not too hard to check but again unlikely
I do my own routine maintenance and minor mechanical repairs but this detailed software analysis and diagnosis is beyond me.
No drivability issues, just a CEL and P010F (both of which have now gone away). Would these be stored in a code history location that the stealer could pull up after they disappear?

It depends on what kind of a job Carista does on clearing things, If the code is gone I wouldn't go to the dealer just because all they can do is slap you with a diagnosis charge if the codes are erased from history. You might have to drive somewhere for 20 minutes or so cycle the ignition and drive back to satisfy the two trip logic requirement.

Ok, soft code then. It may or may not come back but it will be in history in techstream then...if it was a fault in the sensor like an open or short it wouldn't have shut itself off so the ecm saw an out of range between the two. It wouldn't hurt to wait and see if it comes back and stays because chances are they will want to replace both sensors and they might tell you they only come with the upper lids of the air filter housing and you can get them that way but it's pretty expensive.
That code is related to vacuum leaks if MAF sensors check out. There is a vacuum hose running along the left side of the engine that cracks with time, also, as stated above, ventilation hoses need to be checked. I replaced all ventilation and vacuum hoses around the engine when I got the car so I don't have to deal with issues like this.
Might have found the problem. The connector to the MAF sensor on the passenger side harness is broken. All the connectors appear to be making contact which might explain the intermittent nature. It appears to be a common issue now that I've found it - this is one of many pictures on the web. I've zip tied it for now, like the picture, below.
Considering the fact that the dealer was probably responsible for breaking it I wouldn't ask them to repair it, someone most likely leaned on it when doing some repair or broke the locking tab trying to remove the connector.
If it's like the one in the pic the connector's on the harness side and you might get a suggestion to replace the harness that would maybe lead to more breakage....if it's not totally destroyed I would remove the connector from the sensor and check for bent pins etc then put it together with a couple of small zip ties, plug it in and put some tape around the connector. Clear the codes and if they don't come back just forget about it. The connector replacement might not be much fun for you because there's a 90 deg on the back of the connector and it has more tabs to separate the back half and you said before you don't like to do some types of work on your car...I would try the patch like you have and see how it goes.
I had to replace mine, it was very easy. Most people never replace broken connectors, they do what you did until the next owner finds it and does the same thing.

Look like it's US emissions related code. Hmm, that's new for me.
