I know this is just a general question with not much details, but what could cause a DTC P0328 Knock Sensor 1 Circuit High Input (Bank 1 or Single Sensor) on a 2002 Blazer Xtreme w/ a 4.3L V6?

Engine has had a complete tune up. Head Gaskets replaced. Timing was redone. O2 Sensors replaced.

This is my brothers blazer so I do not know what else has been done.

 

If you get a trouble code saying the crankshaft cam shaft corrilation is off then
you need new distributer with shaft and new gear
third one in 85,000 miles for me, bad design by chevy. Good luck
over $500 each time. $300 just in parts
be lucky to get another 10,000 miles out of her

 

Just take the P0327 code and where ever it mentions low input, replace that with high input.

P0327 (S-series) - Knock Sensor 1 Circuit Low Input

Wow... Kinda off topic. Well, completely off topic. And man, you WAY overpaid for a replacement distributor. Besides, that code doesn't necessarily mean that the distributor is bad. But like I said, way off topic.
