    "wires"?

    There's one wire to the knock sensor. It goes to D3 on the ECU. Possible causes of your problem:

    - You're not running the wire to the correct spot on the ECU. You might not be counting the plugs correctly on the back of the ECU. Should be like this:

    D1 D3 D5
    D2 D4 D6

    - The knock sensors you're using aren't good
    - Your ECU is bad

    Is the knock sensor code being thrown exactly when VTEC engages?

    bad wiring, bad sensor. No other causes there.

    I'm having the same prob with my b16a
    since you have replaced the ks twice I'm going to say it is because of your wiring or possibly your ecu
    I have still not solved my problem but need to soon because the damn cel is so annoying when it comes on every time I drive the car

    maybe I'll just take the bulb out :D
