Default Knock Sensor Question - Ferm/Spare!!!

Guys I gotta P0332 Knock Sensor 2 code bein thrown right now on my 05' 2500 6.0

Ive been readin up on it and before I go replacing stuff Im wonderin if yall have any input on my guess on what could have caused it to throw a code.

For one, Ive got a bad baffle in my muffler right now. It'll vibrate/buzz/rattle on initial startup then go away as soon as the engine is warming or about 20secs. Do you think I may be getting some backflow associated with that which may be cause the code to go? As of now I haven't felt or heard a single ping or shudder and the truck is runnin fine.

Other than that I did take a puddle yesterday a little fast in the 3" downpour we had here. Truck still ran fine after I went through it and if that was it then it didn't through the code for another 24 hours or approx. 20mi......

Im leanin towards the puddle due to all the "I was washin the engine and this code showed up" stories Ive read but wanted to see what yall thought....

Thanks

Oh no spare, he has an LS. It is located down in the lifter valley under the intake manifold. You have to remove the intake to change it, so unplugging it isn't that easy. I do know they are VERY sensitive to torque, and most are broken when being installed. And a few people have gotten this code due to an exhaust rattle against the block.

Yep, GM used to put them down in the block drains where they were easy to get to(unless it was the 4.3L where they put them in the heads, still not that bad to get to). For the LS engines they moved them under the intake.

I read somewhere that it can be accessed through the front pass wheel well. Do you know if thats possible?
