What do the cooling system and OBD codes p0327 and p0332 have to do with each other?

Question

On my 2002 Chevrolet Silverado 1500 5.3L, I replaced the head and intake gaskets, and then got codes! What do the cooling system and OBD codes p0327 and p0332 have to do with each other?

Answer 1

When you get P0327 and P0332 this means there is a poor connection at the Knock sensor or a failed knock sensor

.

Here is a knock sensor during a cylinder head change, there is a TSB for both these code conditions TSB # 02-06-04-023A where you are to apply RTV silicone sealant at the knock sensor cover.
