Default Which Bank is Bank 1 on a 2007 RX350?

Hello,

I have to install a new O2 sensor on a 2007 RX350 and was hoping someone could tell me if bank 1 is the front bank or the rear bank?

Thanks,

--Stephen

"Bank one is the side with cylinder one, on that car it is the firewall side."


got this from google. You have a bad sensor already?? How many miles do you have? I always get the bank one bank two thing confused.

Also,that is probably an air/fuel ratio sensor,which is heated as well. Not just a regular o2 sensor.
