get out a multi meter. looking at your distributor connector, the side where the wires go back into the distributor. try to match the wires to the picture bellow.



1 = ICM signal
2 = CKP ( + )
6 = CKP ( - )
3 = TDC ( + )
7 = TDC ( - )
4 = CMP ( + )
8 = CMP ( - )
5 = N/A

disconnect the connector and mesure the resistence bettween pin 3 and 7. you should have About 350 ohms to 700 ohms
some honda's also mesure between 700 ohms to 1300 ohms, cpmpare it to the other two sensors. they all should be the same resistence.

if you want to take it to another step, plug the connector back on and back probe the connector on pins 3 and 7. set your meter to ACvolts, start the engine let it warm up. at Idle the TDC sensor should be putting out aprox 2.3 volts at idle and at 2500 rpm 5.73volts
if you can mesure frequency then @idle aprox 48Hz @ 2500 rpm 120 hz. if you can score an automotive ocilliscope you can tell if your getting glitches in your waveform. like Toda Au said about EMF. I hope you understand this.
