Is my car an OBD1/OBD2 Hybrid?!

[Meeerrrk 0]

Hi everyone, seem to have got myself a bit confused...

i have a 1995 (early, feb i think) Highline. I thought it was an OBD1, it has the smaller rectangle side repleaters, it seems to have the ISV (im pretty sure thats what i cleaned...) and there for, i assumed it was an OBD1, just before the cut off before they started OBD2 cars

HOWEVER, i found out today it has an OBD2 diagnostics connector, not the 2x2 which i was expecting to find. Whats going on, did they make some in the middle ?! Is there a sure fire way to find out which i have?

thanks in advance

Mark

if its got ISV on the intake system its obd 1 mate no matter what diag plug you have ...

as explained in the above thread the easiest way to tell what code your engine is is with the throttle body mate - all other parts - indicators, obd plug etc etc dont confirm anything

Ok, its an OBD1 engine, 100% sure. Funny thing is it has an OBD2 diagnostic connector (good for me!). Still, thanks for the info, very useful

What's the isv Thingy that people refer to? I'm on a 96 n plate. I have the coil pack but unsure what the isv is and what it looks like to confirm my interface type. Cheers in advance.

An ISV is on obd1 models , it regulates the idle , idle stablizer valve if im not mistaken . anyways its a silver/grey valve that is connected off the right side of the throttle body , if you dont have 1 of these then your car is an obd2 model as it most likely is being an 96 model .

theres loads of pics on here jus pop ur bonnet and have a nosey round, but being a 96 like above I would say obd2

Back to the op my 95 highline was the same, later abs and 288mm discs, obd2 maf and diagnostic port but was def an obd1 engine and square side repeaters
