Default oxygen sensor help

my 1998 gs300 got the p0155 error code
which relates to BANK2 SENSOR1 BANK 2 SENSOR 1 i just did that fro search reasons

can anyone provide a sensor location chart or something

from what i understand we have 4 or 5 o2 sensors

the headers are split into 2 im not sure if its cyl 1 3 5 and 2 4 6 or 1 2 3 and 4 5 6

i think its 123 456 i cant see i have a heat shield.

anyway so theres a sensor in each cyl group up top before the cat which are called the upstream and a sensor in each group after the cat

so thats 4 sensors now.

are there anymore after that.

and which one is BANK2 SENSOR1

i know BANK2 is upstream from what i understand

anyway
someone should make this a sticky if anyone has the complete info

bank 2 will be on the side of cylinder #2. Sensor 1 refers to the one closest to the engine pre-converter o2!
