03 Silverado 2500hd knock sensors

[Turtle 59]

Lifetime mechanic. Changed knock sensors in my 6.0 vortec. Drove approx 80 miles and check engine light came on. Same code sensor 2 bank 2. I used ac Delco sensors. Everything else appears to be in order. Any suggestions?

Did you change or check the knock sensor wiring harness?

The 6.0 just has a front and back knock sensor, so it won't have something like a sensor 2 bank 2 designation.  Did you mean O2 sensor?  Maybe post the actual code.
