Code P1128 Oxygen Sensor Question
1998 Boxster 2.5L engine
Error code P1128 – "PCM detected the oxygen sensor 2 for cylinders 1 through 3 was at its lean limit."
Can anyone tell me if “Sensor 2” is before or after the catalytic converter?
Also Error Code P1125 for the same bank - passenger side - "Oxygen Sensor Adaptation, Upper Load Range, Bank 1, Above Limit"
No indication of before or after the Cat. Any advice?

Normaly, sensor 2 is after cat and sensor 1 is pre cat.
With a boxster, bank one is passenger side, ..the opposite as in a 911, because engine is in "reverse" position.
Now, this is to be reverified, as I searched for this some month ago, when I had exactly that same problem !
