Temperture Sensor

I have a 1999 Kia Spotage with a 4 cyl engine has an automatic trans. My problem is when driving it the temperature gauge reads and then it drops down as if the car has been shut off and then it will read again. The temp is fine and I have looked at both the radiator and reservoir and they are at the proper level. My question what could cause this and does anyone no where the temp sensor is and how do I check it or should I just replace it if I can find it.Thanks for your time Huffy.

Re: Temperture Sensor

The temp gauge is controlled by the temperature sender on the engine. It could be a problem with the sender, wiring, or gauge itself. You'd have to monitor the voltage at the back of the instrument cluster to figure out which one of those things it could be.

You might want to start out by doing a visual inspection of the temperature sender and the connector that plugs into it. Pull the connector off and make sure the terminal is good and there is no contamination. Wiggle the wire and harness while someone is watching the gauge to see if it acts up.

Temperature sender is located in the housing the upper radiator hose connects too. It is the sender with the one yellow wire.
