The cali spec V6 has 4 O2 sensors; one in each bank, the pre cat and the after cat.
But I thought cali spec had 3 cats. So wouldn't their be 3 o2 sensors?
I dont know.

as for the oxygen sensors, chip is right there are 4. its on page 15-19 in the service manual. one oxygen sensor before each precat and one after each precat.
