    How do I troubleshoot an error code #9 ??

    I have 95 LS/VTEC with an OBD1 ECU, distributor, etc. using a Conversion Harness adapter.

    I am using a P28 chipped ECU which is looking for the Knock Sensor signal. This initially triggered a CEL code #23 which corresponds to Knock Sensor, but the car idled very erratically.

    In checking it out a friend found out that the plugs were messed up - so we replaced them and the engine sounded much better and revved out pretty nicely.

    But now the CEL #9.

    What could cause this ??

    Thanks for any help.

    p28 ecu's don't have knock sensor circuitry. there's no way it can throw a code for it.

    as for code 9, check your timing betwen your cam gears and crank pulley.
