SOURCE: Temp Sensor
The temp sensor known as the engine coolant temp. sensor tells the computer if the engine is overheating and so forth and tells the injectors how much fuel to give the engine. The temp. sending unit is what controls what your guage reads. It sounds like you need the temp. sending unit. It located near the thermostat housing with a single pole connector.

Look for a loose connection to the temperature sender unit on the motor.
If all connections OK, you may need a new temp sender unit.

Sounds like there may be an air pocket in the system.
Try 'burping' the system. If this still doesn't fix the problem, check the temperature of the heater core hoses (in and out) The inlet should be fairly cool, the other should be piping hot. If they're both cold; the heater core has an internal blockage.
Next, replace the thermostat with a winter (180-195 F) derivative.
Bleed the system accordingly, and keep me posted!

Possible that there is circuit error or the posistor reading is giving erros to the circuit to trigger the LED. If the guage is correct then there is no cause for alarm but to concur and find the solution. so check using a thermometer and confirm which is right. if so the circuit must be checked.
