1995 Ranger Engine Temp sensors, where?

Periodically the temperature gage in my ranger is pinned. It looks as if it's overheating but it's not. The previous owner had a sensor changed twice but it didn't make a difference. I've been told this truck may have two sensors. If this is true can anyone tell me where they are and if it's something that would be easy for me to do?

when in doubt of stock sensors you need to install after market sensor and gauge. what if it really is over heating?

Thanks for your response! I've had engines overheat before, and I'm sure this isn't overheating. My sister-in-law was the previous owner and she drove it this way for a couple of years. If it was really overheating the engine would be toast by now.It will be fine for days/weeks and then the needle will pin almost as soon as you start the truck. Sometimes I don't notice it until I've been driving for a while and I think "what if this time it really is overheating?" I'll get out, pop the hood and it's still cool.

I believe the vehicle has two temperature sensor. One goes to the gauge and the other to the control module. Both shoud be located in the vicinity of the thermostat housing. One way to test the temperature sensor.
Disconnect the wire from the sensor and turn on your ignition. Assuming that your gauge is good, it should read minimum or not read at all. Next, touch the wire to the engine block (ground), the gauge should read almost all the way to max. if the above tests are OK, you got a bum sensor. If the engine was really overheating, you will know it.
