you are the man, i really needed those and knew i could come here :D

 

Where can I find OBD-1 codes?

 

thanks man.

 

These are the same numerical codes as OBD 1 codes also, with the exception of the evap emission codes and heated O2 codes and obviously codes that do not apply to your engine.

For example: if have code 1 on you OBD1 car, still means O2 sensor.
etc, etc.
