I have the code P0155 which refers to the bank2 sensor1 needing to be replaced, what is the easiest way to go about doing this procedure? Any info, tips, links, pics, etc would be much appreciated. Also I am throwing P0125 the coolant temp closed loop yadayadayada, but I've read that it could be related to the P0155 code, so I will replace that sensor first and then see if both codes stay gone after the codes being cleared.

Easy as pie, B2S1, and B1S1 are both the PRE-cat O2 sensors, unplug the bad one, use a box end wrench, 22mm I believe, the connector will fit though the end of the wrench, and take it out. The sensor will be about 100 bucks if you pick it up locally, you can order it cheaper online.

Or, if you have the tools, you can use a 22mm spark plug anti fouler, drill the center of the anti fouler out with a 1/2 drill bit. Thread into the manifold, then re install your O2 sensor( this procedure is normally done for the code P0420)

Easy as pie, just pop the hood and reach in there and do it.

Thanks guys I didn't actually see it until I looked more carefully I thought it was more hidden or harder to get to but now that I've seen it and with the info you guys have provided I am sure it will be a smooth repair thanks again

Changed the sensor out with a brand new oem denso, check engine light came back on...what else can I check?
