    Those codes are
    DTC 9 A problem in the Cylinder Position (CYP) Sensor circuit. (In the Dizzy)
    Check the wiring making sure all the connections make contact with each other, meaure the orange and white wires (Pin B11 B12) for 350 to 700 ohms if not repair the wire, or possibly dizzy and/or ecm.
    DTC 21 A problem in the VTEC Solenoid Valve circuit.
    Check the wiring making sure all the connections make contact with each other, also check for 14-30 ohms on the connector if not replace the solenoid.
