I have a 1995 Ford Mustang GT and my check engine light is on. How do I extract the codes? Do I need a scan tool or can I do it without one?
You do not need a scan tool to extract the codes on this vehicle. This vehicle is OBD I and does not switch till 1996 so you do not need a scan tool. Basically you install a jumper wire or paper clip in the diagnostic test port located under the hood toward the passenger side firewall. Once the jumper is in place, you turn the key on (do not start engine) and the check engine light will flash the code. Here is a link to Complete Instructions and a full list of Ford OBD I Check Engine Light Codes with descriptions of each code: EXTRACT FORD CODES
