Hey thanks 3dfx..Did you find that on the net somewhere? Are there more of the codes that are above 100 ?

I understand that some codes may be the same in number but have absolutely different meanings depending on what system i;e OBD 1 or OBD2...My cadillac is of the OBD1 style.
1993 Eldorado N* 4.6L..


Thanks again..

No prob - btw its TWOdfx! :D

Even though your car is in the OBD1 era, the North* kicks out OBD2 codes. There are many more codes above 100, heres the site I used:

Po109

Hey...on a '93 PO109 is a memory reset code in the PCM. Its listed along with PO52. If your not having the computer reset...ignore.
