If that is true, you can use that as a determining factor to which one your car has.
On most japanese cars I've seen this is a good determining factor.
However I know of at least one that are OBD I and use two O2 sensors.
I know there is something on the ECU itself that will tell you, but I have no idea its actualy say's "OBD I" or if its incorperated into the ECU number.

Try a search for OBD 1 and see what you find.
I believe there is a site called www.OBDII.com or something similar.
