Located on the exhaust pipe. follow the exhaust from the engine, down to one pipe that should have a big bump in it. This is your catalytic converter. You should have an O2 sensor before the converter, and one after it. It takes a 7/8 wrench to get it out, and you'll have to unplug it first.

2000 silverado 1500 4.8 bank 1 and bank 2 to lean how can i fix


I have a 2001 Silverado 1500 with the 4.8 that had the same error codes. It turned out to be intake manifold gaskets were bad. With the engine running spray some carb cleaner on the intake where it bolts up to the heads and listen for the engine to speed up. If it does you've got a leak. With mine I couldn't find the leak with the carb cleaner but after I replaced the gaskets the problem was solved. Hope this helps.
