Thanks again for the info.
I went under tonight after work and looked and looked and looked. I can only see 2 as stated here. My AE Software shows only 2.
B1S1 voltage varies from .1 to .8 and the fuel trim is pretty much around 0
B1S2 voltage is reading 0.00 and fuel trim is 99.03

So, I got the tool and the sensor and changed the one that was easier to get to... The Drivers side. And B1S2 is still not functioning

What I am coming up with is :

B1S1 is Drivers side
B1S2 is Passanger Side.

Is this correct ?

Which is completely opposite to what I have read in other posts...

B1S1 Front Pass
B1S2 Rear Pass Side
B2S1 Front Driver
B2S2 Rear Driver
