Error Code 1126

[Eleung]

Does anyone knows what the generic error code 1126 (obtained on a Snap-On reader) corresponds to in the Porsche world? Does it has to do with the O2 sensors?

Thanks.

Oxygen Sensing Adaptation Area 1 (Cylinders 4 - 6) - Rich Threshold

Not sure if it means the O2 is bad but there a many possibilities like a bad MAF

I replaced the Air Mass Sensor and it seems to have solved the problem.

Thanks to rpagan and CJ_Boxster for your help.
