most likely, missing or defective ignition output signal.

check your wires... see if its unplugged.
if it all looks right, prehaps its shot... trade out with a friend for a known working one. if you still get the code, its not the sensor/unit

could someone elaborate more on this?

I've got a 1992 honda civic cx hb .. and I got a Code 15 error, and I'm totally lost.

What does a ignition output signal even deal with?

Any more information would be greatly appreciated. Thanks
