For a while my pr3 ecu has been throwing code 23 (knock sensor) and 14 (EACV). when i first wired up my car for vtec i followed the web site of hasport using their wiring harness diagram. it says place a single orange knock sensor in b10, and a white wire in b12. well i just found on the hondata website that my knock sensor should be in freakin b19. B19 currently has a green/red wire in it. If any of you can help that would be great. Let me know which spot it should be in and what to do with that green/ red wire. i have an extra chiped ecu that overlooks the knock sensor but i really want to get this right. here are the links so you can check it out.

Those instructions only work if you have a Hasport harness. They're not meant to work as a "how to" when converting a harness. If you look at step 3 in the instructions you'll see that you move a wire from B2 to B19. That's an orange wire that is already existing in the harness. It's different than the orange wire that gets plugged into B10.

 

I do have the hasport wiring conversion. Thats just the problem, ive done everything they said and i have even replaced my sensors with new ones and reset the ecu and i still have the codes. i also have wires in spaces B2 and B4 wich everything else says i shouldnt have.

 

Did yo move the Orange wire from B2 to B19?

Well i went out and checked after your first reply and there is still an orange wire in B2. so im guessing that wire was never moved. Im going to give it a shot today and ill post results. What should i do with the wire thats already in b19? just cap it off? Thanks for your help.

After you remove the wire from B19, just "cap it off", you'll be good.

 

Yes!!! That was it. Thanks so much for your help, ive been working on solving this for a long time. Thank you for your help.

 

Damn I'm smart, Huh Joe?
