Which sensor do I need to replace of the four that could give me a code P1130?

Question

I have a 2000 Toyota Solara SLE with California Emissions. My codekey codes are P1130 and P1130(pd). I can't find any explanation of what the (pd) means. Also, is there any way to know which sensor might be bad? I have four, and replacing all four seems unnecessary if I could identify one bad sensor.

Hi there,

This code is for bank 1 sensor 1 which is the first sensor on the bank closest to the firewall.
