This fault code is more related to the o2 sensor but you can't rule out the MAF sensor because it is part of the system that maintains the air:fuel ratio which is 14.7:1.
I would suggest getting the garage to look at the live data (whilst the engine is running) for the upstream and downstream o2 sensors, you could have a bad/clogged CAT converter or possibly an o2 sensor that's gone bad.
