Code 9--The internal CYL distributor sensor is bad. No viable alternative but to install a new genuine Honda distributor housing.

Code 43--Fuel supply system or heated oxygen sensor circuit. Use a DVOM to test the resistance of the heated oxygen sensor circuit (two black wires). If resistance is infinite, then the circuit is bad and you will have to install a new oxygen sensor.
