they are very easy to replace .
all you need to do is go to autozone and get the right parts.
then you will find the old parts on the exhaust system.
unplug the first one you find and unscrew it from the exhaust and refit the proper replacment part.plug wire back in.thats all you will need to do on the second one also.after that your done.ask auto zone after that to reset your codes for free with the code checker.then get a can of carb cleaner and spray out the throttle body of all the black carbon around the throttle plate.use a clean rag only.make sure its clean around the plate.
thewn fill your gas tank with supperunlead dont get the crappy gas any more cause it causes the carbon to build up.plus you will get better gas mileage.now your ready for an inspection sticker.
hope this helps
keep me posted

bank one sensor 1 is the bank of cylinders that number 1 spark plug is located in, bank 2 the other side, this assumes u have a V8, the sensor one location is the sensors that are BEFORE THE CATALYTIC CONVERTER, the sensors referred to as sensor 2 are after the ones AFTER THE CATALYTIC CONVERTER IN THE EXHAUST SYSTEM.
