If both knock sensors are throwing a code, can they cause a reduction in engine power? I have an 05 Tahoe with a 5.3 that is struggling to get out of its own way right now, I’ve deleted cats and changed plugs, replaced the purge flow solenoid as well. With none of these helping. It’s throwing so many codes I’m not sure where to go next.
The wiring harness to the sensors can also be replaced seprately, could it be a wiring issue? Wire nick,cut etc.
Deleting the cats will do that
I have same problem but brought on by my own stupidity. I hate to invest too much in this 5.3 motor as I plan to build a 6.0 just haven't found the block yet. I power washed behind my water pump when I replaced it. Then put everything back together. I think some of the water got under the intake and into the knock sensor (my guess). Now I'm throwing P0332 code
I'm not sure if P0332 indicates I wrecked one or both of the knock sensors under the intake. And if I can get by with one bad knock sensor. Truck runs fine otherwise.

Ah I didn't realize your post was for gen 4... I have a gen 3.Gen IV knock sensors are not under the intake, they are located on the bottom sides of the block.
