i put a b16a into my 90 integra. my check engine light comes on and code 23 comes on , wich is knock sensor. its already connected and i have tried everything!!!

 

Have you tried replacing the sensor? Did you check the connection at the ecu plug?

 

Search, and you'll find you need insulated wire.

I honestly have answered this question more than 5 times in the last couple weeks >_<

So have I. You should use shielded wire for the knock sensor which shields out electrical interference's from other electrical parts and sensors. There's going to be people to say "I never used shielded wire on my setup" as always. Well, they are fortunate enough to not need it, but most of the time you do. It is wired that way from the factory (get a Helm's and you'll see) for a reason.

 

i have already tried a shilded wire but no results.

 

The only other possibilities would be that you aren't connecting the knock sensor to the proper ECU pinout or the sensor is bad. It could also be loose in the block and might need tightened.
