I have seen this before more than likely your coolant sensor has a internal short and needs to be replaced.
There is a sensor located at the bottom of the coolant reservoir.
were is the cooling temperature sensor located on my 96 Plymouth grand voyager
you can't reset it, fill your coolant up full, both rad and overflow. the light will go out. if it is still on when everything is full, then your coolant sensor is broken or unplugged. if you light goes off then comes on again and your coolant is low, then you have a leak. if you have a 3400 engine in your lumina common leaks are intake gaskets, waterpumps, and head gaskets.
Yes, a faulty coolant temp sensor can do that.
Sounds like your cooling fan relay is shot. Ron J.

Might be the sensor, each fan has its own relay

Is the car overheating? As a safety measure, the fan will come on when the coolant sensor is unplugged. This is in case the wires come unplugged or the sensor goes bad so that the car will not overheat. If you have A/C the fan should come on within a few seconds after turning the A/C on. The fan on the car does not come on simply because it is plugged in to the sensor. It first has to get fairly hot....something like 238 degrees before the fan will come on. This is a how a correctly functioning fan will work. If it is not coming on when the gauge reads above that you may have to take it in to find out why. It could be a bad sensor....likely......or that the computer is not reading the signal correctly and thinks the car is running cooler than it is.
odds are the sensor needs to be replaced
check to see if the cooling fan temp sensor is unplugged. the sensor is located on the drivers side of the engine. the heater hose comes in from the back of the engine. there is a manifold with two sensors plugged to it. the one toward the rear of the car is the one. if this is unplugged the engine light will stay on and so will the fan. if this is not the culprit there are quite a few things that can make this happen.
Many possibles, coolant leakage,headgaket,plugged radiator, stuck thermostat, bad cooling fan, coolant sensor, radiator fan relay, ECU malfunction, rodents chewed on the ground wire for the cooling fan, or about 20 other possibles
Sounds like the coolant sensor is unplugged....or possibly a bad sensor. Check to make sure it's plugged in...replace if needed.
No, the electric cooling fans turn on and off by a signal from the coolant temp sensor. The coolant level sensor only illuminates the low coolant light when you are low on coolant.
Where is the temperature cooling sensor located
The low coolant sensor is located in the side of the radiator. It can be unplugged but then how will you know it is low.
