P0332 code. Knock sensors. Problem. Help. CEL stays on.

[ERK1990]

I have a 2001 Tahoe 5.3 4wd 134k miles. Just bought it about a week ago. Picked it up 4hrs away. On way home CEL came on. It is a P0332. Bank 2 knock sensor 2 low circuit. So I got it home and went to my chevy dealer picked up 2 knock sensors, intake gaskets, knock sensor wirin harness with boots, ...replaced it all, silicone around the boots. Cleared the CEL with scanner. The. It came back on after about 30min of driving. So I cleared the light again... And it came back on after about 30min of driving (I haven't checked it the 3rd time..but do believe its gna be same code). ....so what's going on? Is there something else make the light come on? Will my tahoe be in limp mode? What can I do to fix it? ...Thanks

Disconnect the two wire harness at rear of the intake and measure resistance to each wire and ground. You usually have the replace the harness also. Did you use a torque wrench?

What is the torque on the knock sensors?
Intake is 44 in lbs then 89 in lbs correct?

Thanks
