Replaced ks still getting 0304? HELP

Hi my ecu has been pulling 0304 for months now with no other codes. I reset it and it would come back so the other day i put the new knock sensor in and cleared the codes, checked codes 2 days later and it was back(0304). Cleared Ecu again and checked today guess what i pulled 0304. So now i have a brand new ks in there and my ecu is still getting codes for it. What is the problem? The old one was bad bc i checked it and this one is in spec when its cold but when it gets hot the resistance drops to .35m ohms what the hell is wrong please help!

Sometimes the KS harness goes bad.
