while we're on the question of codes

my car threw a 0043 "HO2S heater control circuit low (bank 1 sensor 3 ) what does it mean . the guy at auto zoned told me "ah, its either a o2 sensor or a cat". thanks for the expert advice , the car has 4 o2 sensors and 2 cats. can we narrow it down because if its the cat it still under the extended Chevrolet warranty of 10 years or 100,000 miles. good karma to all that help!

thats what the "gentlemen' said at auto zone , why? i didnt actually see the scanner and my info is from here....http://http://www.ls1.com/forums/sho...ight=obd+codes actually he said about the 02 or the cat, i looked the code up myself from the link

P 0043 is a Generic code that doesnt apply to our cars, Bank 1 Sensor 3 doesnt exist.
Bank 1 sensor 1&2
Bank 2 Sensor 1&2
Either way if its an 02 sensor its not coverd under the warranty although if its a cat it is covered.
I would recomend you getting the code scanned again and actualy viewing the scanner and then post up the code..
