I just did a jdm h23 vtec swap in my car and currently have a P0325 check engine code coming on that I can not get rid of. It is a Knock Sensor Circuit Malfunction code. I have run through the Helms Manual Troubleshooting diagram and have not found anything wrong. I have replaced the knock sensor with 2 new ones (both Duralast brand from autozone, I know they're not the best but honda can't get them for a few days). I can't figure out what is wrong. I did notice that my E-Brake light flickers so I am thinking that a bad ground wire could be the cause, but not sure. Anyone have any ideas?

I just think I found it the problem, there was a ground wire spliced into the knock sensor wire before the ecu which was causing a short. the light is of for now, but we'll see if it stays of. Thanks for your input though usmcmarc, that would have been my next step.
