I read the sticky regarding error codes and followed the instructions exactly to obtain an error code or codes as to why my check engine light is on, but unfortunately no codes appear, it just shows my odometer reading. If no codes appear does it mean I'm doing something wrong or there's nothing wrong? I find it hard to believe the latter, the check engine light doesn't just come on for nothing does it?
I forgot to mention it's a 2004 Turbo with 67K miles.
