"OC" means "Open Circuit." On a '99, the thermocouple is right under
the RAM emblem on the front of the hood, forward of the radiator.
Look for a broken or disconnected wire. BTW, "SC" (looks a lot like
"5C" on the display) means "Short Circuit."

99% of the time, when you see OC it means the thermcouple failed. It
"could" be an open wire but probably not.

Personally I have usually found the stupid connector has failed.
Sometimes you can clean 'em and restore, frequently you end up
replacing both the thermocouple and the connectors. Ouch!

If we could only talk the engineers into using a dab of di-lectric
grease on assembly.........
