O2 sensor V70-XC70 1988

Looking under the hood down to the oxygen sensor connectors, which on is the bank 1 connector?

    There are 2, the gray one is for the rear. This being a straight 5 engine, there is no bank 2.

      So both O2 sensors are for bank 1?
      Which one does the OBD code P0133 pertain to?

        Unless you have a V4, V6, V8, V10, V12, there is no bank 2. Remember, these codes from your scanner are generic, meaning all engine types.

        P0133 is the front O2 sensor, before the CAT.
