Ok, understood.
Maybe just a naming difference? The seems like still 4 sensors? All have data output on your scanner? Well, except the one you said could possibly be failing?
I'm not familiar with the 4.3 Vortec on the GMT400, but I seem to recall reading here there's something different compared to the V8 exhaust. Just one cat? I don't recall. @df2x4 has a 4.3 truck and knows for sure.
They must have changed this, because on the GMT800 the exhaust between the V6 and V8 is the same.
Edit: sorry, I just saw previous post...
