it should be found on the thermostat cover it is a brass sensor with wires running out of it but when you take it off be carefull or it will break the cover and you will be in a mess of trouble
If the guage is not working check the passenger side of the f-150 toward the transmition under the exhalst manafold there is a wire that looks just like the oil pressure senser wire that goes onto a temp switch that also could be bad or the wire with a small 90 degree boot on it could have came off.
(based on a 96 civic LX) I believe the engine coolant temperature sensor is located on the side of the engine (opposite of the camshaft). If you need more details, I would recommend you to download the service manual on www.manualnguide.com
Coolant Temperature Sensor
The coolant temp sensor would be located between #3 & #5 spark plugs. The air charge temp sensor would be located in the air intake snorkel between the air filter box and the throttle body.
If it is a temperature sensor, it is usually located on the top of the engine near the thermostat. If it is a "low coolant sensor", then it is located in the radiator (it will be the only item in the radiator that has a electric wire going to it) Either way, you would drain the coolant enough to be below the sensor, and then remove it and replace it with a new one. They are usually under $10-$20
That would be the electrical switch right beside the thermostst housing and is screewed into the intake manifold.
That would depend on which temeprature sensor you are asking about. Is it the coolant temperature sensor or the air charge tenerature sensor you are asking about?
The temperature sender (the sensor that sends the temperature signal to the gauge) has to be immersed in coolant in order to correctly read the temperature. If the coolant is so low that it leaves the sender high and dry, the temperature shown on the gauge will not be a true reading. if the sensor is not immersed in the coolant, there a big chance it wont read at all...
Unplug the coolant temp sensor and check what the gauge says...If it falls to cold, then the sensor is at fault. If it stays, then the gauge is either faulty or the contact points on the back of the gauges need to be cleaned...

Why would the temperature gauge indicate an overheated condition when the engine is not hot. It could be the gauge in the instrument panel. Unlikey however. More likely it is a bad coolant temperature sensor or the wiring from the sensor back to the instrument panel. Inspect the wiring and replace the coolant sensor. The sensor is not too expensive.
Have you checked your temperature? There are two sensors one is for coolant level, and other is for temperature. First make sure your not over heating, then disconnect your coolant level sensor located on your coolant tank, and disconnect it. If light goes out, this may be your problem. Although I am not one hundred percent sure this would work as way of testing, because the circuit for level sensor may only come on when circuit is broken. This means you would have to do a jumper wire in the plug for level sensor, and see if light goes out.
Check your coolant level. If its too low the sensor won't read the temperature of your coolant.
