The service manual for my '94 Civic says that DTC 10 and above are "a
series of long and short flashes". I would think, but have never seen,
that 10 would be a single, long flash and that 20 would be two long
flashes. "10" is the intake air temperature sensor on my car and it is
easy to unplug. I'll try it one of these days.
