P0141 on a Lumina

'96 Chevy Lumina w/3100 and AutoTrans
I got a lit MIL and a P0141 code
Says:
O2 Sensor Heater Circut Malfunction (Bank 1 Sensor 2)

I figure the heater circut malfunction means it's most likely the O2 needs replacing, but I want to confirm this
And also which one it is
Is Bank 1 the driver's side, and Sensor 2 the sensor after the cat?
Thanks in advance

probably is the o2 sensor when a heater circuit failure occurs most of the time.
should be the sensor behind the cat.
bank 1 is always the bank with number one cylinder wich i believe 1,3,5, is closest to the firewall and 2,4,6 is near the front of the car.
