WARNING: This page is about a different car, the 1994 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.
These codes result from information stored by PCM during continuous self-test monitoring.

These codes indicate faults previously recorded. Fault may or may not be currently present. See SERVICE CODE-TO-TEST REFERENCE MENUS .
