Check the coolant level. I would also drain and flush the coolant system and change the thermostat. Make sure the cooling fans are working.

There is a seperate sender for the temp. gauge which may be bad, or the waterpump may be bad.

Scan the PCM to see what the PCM is showing the coolant temp to be.
