993 Oxygen Sensor ( x4 ) layout...?
 

Does a Pelican know the location (righ / left; pre- / post- Cat) designation of the respective four oxygen sensors for the 19969 -98 993 p-cars

I use an OBD software to monitor (in real-time) the voltage waveforms but need to attribute the corresponding signal to each of them:

Bank 1 ( Ox-11; Ox-12 ?)
Bank 2 (Ox-21; 0x-22 ?)

Thx.

on the 993, bank 1 is drivers side of the engine, 11 is before the catalyst, 12 is after the catalyst

bank 2 is passenger side, 21 is before catalyse, 22 is after cat.
