SOURCE: code P0157 and P0137
P0157 02 Sensor Circuit Low Voltage (Bank 2 Sensor 2)
P0137 02 Sensor Circuit Low Voltage (Bank I Sensor 2)
There is something that could be making the air and fuel mixture incorrect causing these codes. It don't necessarily mean you need new O2 sensors.

the bank 2 sensor2 is used to check that your catylitic converter is working on that side of the exhaust. without seeing the car and doing sensor tests, it would be a gamble to say replace the sensor. so you can replace it and see what happens or take it to your favorite shop for further diagnosis
