OK, I found my self test port (Thanks Theo!)

Now for the next problem. My truck is OBD I and it uses an OBD II port. Profanity Removed!?

I have an OBD I code reader that uses an OBD I port and I have an OBD II code reader that uses an OBD II port. But I don't have an OBD I reader that uses an OBD II port.

Is there some adaptor I can use or something?

How do I read codes on a 1995 PSD?

Thanks!

Mike

 

check with Advance Auto Parts. The local store here had some type of adapter that I believe may be what you are looking for.

 

I have a 1995 PSD and I can tell you that whole ODB I with an ODB II port is complete BS. Mine is an ODB II. I bought a superchips programmer and was able to read all my codes and give my truck more horsepower not to mention they shipped the programmer overnight. Most code readers sold at the auto parts stores will not read the PSD computer for 1995 PSD's

 

The early powerstrokes use an eec4 computer system, most of them have a ob2 connector inside the cab but it is not hooked up. Ford made a wiring harness which would connect it but I do not know if it is still available. The data from the eec port is not nearly as complete as it is from the ob2 system. Hope this helps.
