I went to AAP today to scan my pcm to find that the connection was for an OBDII fitting. I am confused. I thought OBDII didn't start until 1996. Also, I got my pcm from a 94 z28? What the heck is going on here?

 

late 94 and up had OBDII.

 

OBD II wasn't until 96, you're right. That's weird.

 

in 95 the cars cam with the OBD2 port but they still have OBD1. OBD2 didnt start until 96

 

First correct answer in the thread

 

To clarify.

All 94 Fbodies are OBD1
All 95 Fbodies are OBD1 BUT use a OBD2 port
All 96 and up Fbodies are OBD2

your 95 isnt a freak job or anything its just built differently lol. Dont be alarmed your 94 PCM will work jsut fine also.

 

Yup...^ they are right...I have worked on a few '95's with dual cats though! I believe they were california cars though!

 

Some late 95 california cars were OBD2. Not sure how common they were, but Ive heard of it.

 

My 95 is OBD 1 with OBD 2 port

 

How do I know if I have a California car?

 

95/96 was a lil change year for f-bodies. If I remember correctly, even the 02 sensors were changed from a flat connector to a square connector?

 

Not true.

TransAm9585 has the right info, but it should be clarified to say
95 LT1 f-bodies...

If you have a California emissions equipped car, it will have RPO code
NB6. It still won't matter. If it is a 1995 LT1 in an f-body, it's OBD-I.

 

Missed a few keys lol. It is LT1 fbodies. Thanks for catching that one Shoebox.
