Actually, the way GM numbers them, any of the sensors with exhaust from
the #1 cyl flowing past it is considered Bank 1. Thus, the one after
the cat is called Bank 1 Sensor 2.

However, if it's a dual cat setup...then you have 4 sensors, bank 1
sensors 1&2, and bank 2 sensors 1&2.

The parts guys just love trying to figure it out, because their book
names them altogether differently(something like positions 1, 2 and 3).

If I was the engineer, I'd design the two before the cat the same, and the
two after the cat the same. If it was possible to make them all the same,
then that's what I'd do.

Frankly, there isn't much to an O2 Sensor, and the automaker doesn't even
design them, they buy them off the shelf someplace. The main differences
(besides front and rear) is the connectors, and these can easily be made
uniform to avoid a half-dozen different part numbers.

Chrysler does the same thing. The guys who write the service books don't talk
to the guys who write the parts books. One part can have 2 different names,
depending on who you talk to. O2 sensor location is always tricky also. Some
aren't even listed by location, just by the length of the pigtail, which is
really stupid.

if u have a v8 bank one will be the head the contains cyl.#1 and o2 1/2 would be
bank one downstream o2 real easy
make sure u check the cat.(see if it ratles) a failed cat can set the same code
