My car DON'T HAVE CATALYTIC FOR MORE THAN 10 YEARS AND EVER SHOWS ME A CEL THIS APPEARS LIKE A FEW MONTHSYes that would be sensor B2S2 sensor 39210-37540. You can still use B1S2 39210-37525 in the B2S2 location... The only difference between those two sensors is the extra heat shielding on the B1S2 pig tail. Otherwise they are almost identical in pig tail length and they operate the same. If you had to, you could swap them no problem.
Do you have headers installed? If so, the voltage too low CEL might be caused by the catalytic converter delete. You might still have the check engine light even with a new sensor. It's not a critical sensor that's required for air to fuel ratio calculations. If PR doesn't have emissions testing you don't have to worry about the downstream O2 sensor check engine lights. I personally don't even use my downstream O2 sensors. I drive with a CEL all day every day because it doesn't affect performance. Only the upstream sensors could affect your air to fuel ratio and hurt performance.
