Default 2003 WRX HELP! Knock sensor!

I have a 2003 wrx with about 50k on the motor and I am throwing code p0328 knock sensor high input. Replaced the knock sensor because thats all I read on the forums was everyone saying replacing it fixed it. It didn't make the code go away. I did the age old test with a multimeter on ac current and tapping the block with a hammer but no dice.... didnt register anything. Now I dont know if that test doesnt work because WRX knock sensors are tuned for just ping which is like 6000-7000hz which I obviously can't replicate with a hammer buttt idk... I am stumped. The car doesnt really hesitate, the code just wont turn off and I don't hear knock whatsoever. Anyone have any ideas how else to test it or what else to do? Aftermarket knock light? I need this car tuned and they wont tune it without hte knock sensor!
