Default Testing knock sensors?
Any good way to test if your knock sensors are working in a safe/effective manner with hptuners or somehting? I relocated my knock sensors on my 404 and been driving it but i havent seen a single degree of KR anywhere and ive driven quite a bit.

The best way I have found to check them is to monitor the knock voltage and use a hammer to LIGHTLY tap on the engine near the sensor. You should see a change in the voltage.

I can't find a PID to monitor knock sensor voltage, any help on that or any other way to test these things?

just monitor KR when doing the tap test, if the KS is reporting it will show up

If you still haven't gotten the results you were looking for, you can use a digital multimeter to monitor the output voltage of the sensors while lightly tapping on the block near the sensor.
