Can someone tell me where bank 1,bank 2,senosor 1,and sensor 2 locations are?

 

B1 = bank 1 = cylinders 1,3,5,7 = LHS = driver side
B2 = bank 2 = cylinders 2,4,6,8 = RHS = passenger side

S1 = front sensor = pre-cat
S2 = rear sensor = post-cat

So...

B1S1 = LHS front sensor
B2S1 = RHS front sensor

B1S2 = LHS rear sensor
B2S2 = RHS rear sensor

 

Thanks Joe I appresiate it
