'95 Firebird Formula OBD code 11??

Was getting ready to run up state for a friends wedding yesterday morning, stopped at the store for a minute, and when I restarted the Firebird I got a CEL. Ran back to work (Auto repair shop) and scanned it, and got Code 11, Malfunction indicator light circuit...

WTF.. the light came on, and when I try to reset it it goes out, showes "codes cleared", then pops right back on again, and the fans start running.

Anyone ever seen this before? What's the fix??

I've never heard of an GM/OBD1 code 11.

That's what I was looking for!! Thanks VetteOZ

As a note the code cleared itself overnight, and hasn't come back since...
