which o2 sensor is bad

[skog]

the GF's 99 sport with 115k had the check engine light come on.took it to the local checker auto and they hooked the reader up to it and said bank 1 sensor 2 O2 was bad. The guys though that B1S2 was the front one and B2S2 was the rear one. Is this correct?

thanks

Bank refers to cylinder bank, which for the I6 is always bank 1. I believe this means the rear sensor is bad.

Prolly the rear sensor went out
