      Could anyone verify for me that bank 2, sensor 1 (PO153 OBDII code) is referring to the O2 sensor on the driver's side closest to the engine? Thanks.

      "I believe" that Bank 2, sensor 1 is the passenger side, front sensor. B1S1 is the driver side front. The "monitor" sensor, after the cat, is commonly referred to bank 1 sensor 2.

      Thanks... I also just heard back from a buddy who used to be a ford mechanic and he said that bank 1 is always opposite the #1 cylinder, which on this V-6 is on the passenger side, meaning bank 2 is actually the driver's side and sensor 1 is still upstream of the cat. Just need that third opinion now to help decide. Thanks for the reply.
