2003 Toyota Tacoma V6 41,000 miles.
My check engine light recently came on. I hooked up my code reader and it read a bad oxygen sensor. I have a sensor right before the converter and one after. How do I know which one is bad?

SENSOR 2 IS AFTER THE CONVERTOR
BANK 1 IS THE SIDE THAT CYL # 1 IS
CHECK FUSES BEFORE CHANGINE SENSOE AND CHECK THE WIRE AND CONECTION
GOOD LUCK
