Hmm are you tuned with Osiris? Our cars can be picky from car to car whether they will play nice with replacement sensors so I always stay OEM. I have never seen a MAF throw this code but that doesn't mean it won't.
After changing the O2 sensor, did you go through the Mixture Ratio Self-Learning process? Here's the link.
