OBD2 is 'fly by wire' where accelerator to throttle body connections are electronic. There are 4 o2 sensors - the original 1 per bank, and 1 more per bank after the cat. The benfit are: 1.) supposed to be easier troubleshooting at the shop, and 2.) better emissions control..

Yes, exactly. Drive by wire is not mandated by law and so has nothing to do with whether a car is OBDII. It's just coincidence that both were implemented on the NSX in the same model year, 1995.zahntech said:Few cars are drive by wire, all cars after 1995 are OBDII,and 1997 for light trucks, OBDII allows you to access and monitor the sensors and switches with a generic scan tool, OBDI does not.
