OBD2 has a couple more sensors, and more possible CEL fault codes. For example OBD2 has a 2nd oxygen sensor just to measure whether your catalyst is still working.

OBDII is a different standard which includes alot more emission and diagnostic tools controlled by the ecu. 2nd 02 sensors, crank sensor, maintnace light, just to name the few. also reworked code which is more restrictive. new ecu/harness plugs.
