P0155 Oxygen sensor code on 2002 alphard help.

[charlie1278]

Hi I have recently brought a 2002 alphard and it has come up with a p0155 bank 2 sensor 1 code. Would someone be able to tell me which bank is which and if the sensor circled in the photo is the one I need to replace?

 

Thanks

Bank one front one you also have one on the rear which is bank 2 there are 4 oxegen sensors on the 3.0 engine

Hi thank you for your responses. Okay so it's the rear sensor I need to replace. Can this job be done from the top under the bonnet by removing some parts or will the whole car need to be raised and fixed from underneath? Also is there a way I can find a part number for it?
