Temperature sensor is in intake manifold.
Water is not flowing smoothly through the manifold.
2 immediate things to try........
1. Replace the thermostate (about 6 dollars). If you drive the car to an Autozone for the thermostate purchase, they will show you where it is located and how to replace it.

2. Flush (thoroughly) the cooling system. No shortcuts here, buy the flush and follow directions. Have the heater turned on HI.

After the flush, fill with 50-50 antifreeze-water.

Problem within engine are done. Other issue MAY be the sending unit (as your Autozone guy about that... it looks like a spark plug and takes about 3 minutes to replace.

Most likely you have a stuck thermostat. First try turning on the heater to see if the temp gage needle remains stable. If it does not you should replace the thermostat located under a rounded flange by removing two bolts, lifting out the thermo and inserting the new one in same orientation as the original. Make sure any gasket is properly seated before replacing the rounded flange over the thermo. Also, it is a good idea to back flush the cooling system periodically. Make sure your coolant level is at the neck of the radiator opening and that sufficient coolant is in the reservoir.

Also do not use normal hose water when filling dex-cool systems. You must use distilled water.

SOURCE: It is a 1999. The temperature gauge goes up and

It sounds like you need to change the thermostat in the engine it's located inside the throttle body of the engine the main hose running from the engine usually the bigger hose. Or you might need more antifreeze or a new cap on the expansion tank where you would pour the antifreeze and or it could be a plugged up radiator. But I would check the thermostat or replace it and replace the cap. You can purchase the right ones for the vehicle at any auto parts store and you can ask them to look up the parts you need just make sure you know the make, model, year of vehicle.
PS don't buy the part's at wal mart or any store like that because they cant help you and they don't know what's right for your car.
Good Luck!

SOURCE: my temperature gauge keeps going up and down when

pull off the hose at the top of the motor, if you can see the thermostat try pushing on the center with a screwdriver, it is most likely stuck open. You may be able to free it by pushing the center back and forth till there is no longer any resitance, but it needs to be replaced. As for the temp sensor, if it is bad the guage will flicker, representing a bad connection. If the gauge just rises and falls by pattern the sensor and wiring is probably fine.

I have a Daihatsu terios kid 2002 Motor fan not operating temperature gauge is normal about center of the gauge

The fan only operates when the engine/coolant temperature exceeds the thermostatically controlled fan. At idle observe the dash engine temperature and fan. Before the gauge reads above normal the fan should operate.

2000 dodge stratus. Heater only works at idle, when driving at high speeds, heater blows cold and thermostat gauge goes to cold. Back flushed heater core, new thermostat any ideas?

I'd say you have a faulty thermostat, be it new or not. If your temperature gauge goes to cold as your engine is taking you down the highway, the thermostat is not doing its job. The temperature should never come down to below normal until engine is shut off...

Temperature gauge is fluctuating while driving.

I'm thinking the coolnat level is low, and this might be caused by a bad head gasket - At least $800 to fix - sorry.

Honda 98 CRV temperature gauge goes way up after an hour on hwy

You will need to change your thermostat as it is stuck and is not responding correctly to temperature changes. Have your mechanic change the thermo, do a flush of the system and all should be good again.
