    o2 sensor

    I'm a newbie that just purchased a 2000 camaro Z28. It has slp headers feeding catalytic convertors. My check engine light just came on and my Autoxray says my "o2 sensor heater circuit malfunctioned ( bank 2 sensor 1) " The cats have a sensor in front and behind the cat. Can anyone tell me which sensor to replace. I've ordered shop manuals but haven't received. I 'd appreciate any help.
