Are they identical: the Bank1 Upstream Air-Fuel ratio sensor and Bank2 Upstream Air-Fuel ratio sensor?

Depends on who you get the parts from it seems.

Toyota says 89467-41040 for B1S1 and 89467-41030 for B2S1

NTK B2S1 shows as part 24658
NTK B1S1 shows as part 24822

But Bosch and Delco say they are the same part.
