What year did NSX become OBD-II?

[havoc]

Tried searching, but the search engine doesn't like 3-letter words.

Did manage to find that it was 1995 in the US, but also that someone here with a '95 car had an OBD-I system...so I'm not sure.


(Basically, I've got an OBD-II reader from when I had CEL issues with the S2000, was wondering whether it would work or not...)

When it became DBW I think 95 96 depending on registration, it became LEV later on 2002 I think.

In answer to your second question, try it.
As to the first question mine is a 95 car, it is DBW. I believe it to be OBD-1, it responds to the 'paper clip' jumper with codes as [say] a non-DBW OBD-1 car would and, it only has 2 x O2 sensors [one per bank ahead of the cats].
My speculation is that the OBD-2 would have come in with the 3.2 engine, which had 4 x O2 sensors [ahead of and behind each of the cats].
Observation of the cats fitted to US cars shows a interim pattern for the 3.0 DBW cars which my car certainly hasn't got, so, there may be variances between different markets.

If you have an OBD-II port under the glovebox, your car is OBD-II. Otherwise it isn't :D

"Martin"'s green '96 is definitely OBD-I so I imagine yours would be too.

The ABS ECU still works with a paperclip even on OBDII cars.

My '98 EU NSX does not have the OBD2 connector under the dash....
My '98 US NSX does have the OBD2 connector under the dash

Thanks all for the advice...I'll check later on, but it sounds like it's a "no".

Ah well...
