According to a national database of repairs for the 2001 Chevy Tahoe with 5.3L engine, other than the oxygen sensor, the only other thing that could cause that code is the fuel filter. In my experience the oxygen sensor usually takes care of the problem.

i still keep getting the insufficient switching on bank 2 sensor 1 after replacing the 02sensor twice (i using denso 02sensor 234 4339 oem ) .i wonder if the exhaust leak can be the cause of this? i have 2 broken manifold bolts but its on the bank 1 side and no issues with the sensors. its a trailblazer SS v8 6.0. i also reset the SS by removing the battery twice. to see if the problem is still there. drove 350 miles and check engine light came back on again.

It is possible than the leaking exhaust will trigger the code, even if the problem is on Bank 1. I would definitely fix that problem first.
