There are 4 oxygen sensors on the 2002 Avalanche, located on the exhaust pipes directly behind the engine. You'll have to put the truck on a rack or crawl under it to see them. Two are located on the left side of the exhaust system, with one on the engine side of the catalytic converter, and one just behind the converter. There are two more on the right side of the exhaust system in the same location: one before the catalytic converter, and one after. You'll be looking for a "tap", or an insert into your exhaust pipe, with a single wire coming out of it. The wire is connected to the oxygen sensor, which is screwed into the "tap".
