Catalytic Converter help

[Tadd]

Hello All.
I was wondering if I may get some help. I keep getting code 2237 Bank 1 Sensor 1 and code 2240 Bank 2 Sensor 1. Can anyone take a minute and help me with the right part numbers so I can replace the sensors? 128K miles on my vehicle. Thank You.

You should post the year, make, and model of your vehicle.

You should be able to determine the part numbers from any dealer or parts store, using your VIN.
