P0131 - Oxygen O2 Sensor Low Voltage (Bank1, Sensor2)
P0151 - Oxygen O2 Sensor Low Voltage (Bank2, Sensor1)
Different banks, different sensors.
IIRC (heavy on the if, my memory ain't what it used to be):
Sensors 2 are just used to check the cats' performance.
B1-S1 is used for engine control.
The ECU doesn't use any Bank 2 sensors (MAF, Intake Air Temp, &c) for engine control.
