Sensor 1 is the HEGO and the important one. Sensor 2 only monitors, NO control of engine computer or fueling events . BUT indicates the catalytic converter is having a problem. Tell the seller to forget about the 02 sensor there only approx $60... Tell him you want a NEW CAT converter installed then you will purchase. Regards
