One sheet I found said for the "LH" bank.
How many miles on your engine, have you ever changed your 02's?

Thanks for the help.

Is that the left side when sitting in the vehicle or standing in front and looking at it? I haven't replaced any of them and know it is time. 90,000 miles.

Is the one code for the upstream and the other for the downstream on the left hand side? That is my guess

At your mileage, I would replace both front 02's and clear the codes, see what happens.
