After driving a few miles the CEL came on. I plugged in my Durametric and got the following codes
P0154 Porsche fault code 18 02 sensor ahead of cat. conv. bank2
P1130 Porsche fault code 361 Oxygen sensing adaptation idle range bank 2 exceeds limit value
Question: Are these codes indicating one of my pre cat 02 sensors have failed?
And is bank 2 the right (1-3-5) or left (2-4-6) side of the engine?
Any other information would be appreciated.
Thanks in advance.

DTC No. P0154
Fault conditions :
Open circuit in signal wire or ground wire
Oxygen sensor heating not functioning
Output stage in DME control module faulty
Internal resistance too high
Fault area:
Wiring harness
Oxygen sensor
DME control module
The P1130 code looks like it's set if the O2 sensing for that bank is not working. Investigate the Bank 2 O2 sensor first and then if that's fixed, the P1130 should go away.
