I have diagnostic connector with special plug under my hood

I have obd2 code reader with conventional 16 pin connectot

Can I find adaptor....or maybe my 94 is not obd2

Plug under the hood is Just the engine diagnostic box.
Pre OBD2.

Good for you. It cannot read non-obd codes though.
Just jump TE1 and E1, the engine check light will
blink out codes.

Some early '95's were OBD2 in the US. Not sure in Canada.
'96 was the 1st offical year here.

are we talking 3sgte or 5sfe? (u mentioned two engine codes, and im TOTALLY confused)

USDM 94 - 95 are OBD1
USDM 96-99 are OBD2

^its fact

Now if your talking CDM i would still say its the same.

JDM...(3sgte) i have no clue.


edit: for sucky grammar
