well it could possibly have a burnt valve........Could be the Control Unit
Have you checked the coolant system. It could be because the head gasket is blown and you are unable to hold coolant, causing it to overheat. Good Luck
The sensor may be defective/broken. I would have that checked or replaced.
Could be a problem with the wiring from the computer to the sensor.
Have you checked the cars thermostat?
If an engine light is still on after replacing a fan's radiator sensor in a RFW engine the coolant sensor should also be checked. If the coolant sensor is bad it will send an error code to the car's computer.
It could just be that the water pump is not properly working. Have you checked all the could-be causes for your car overheating if not then do so.
you prob need to have your coolant checked out because when you work your engine the coolant is what keeps it at a good level so you should have the mixture of coolant to water checked out it should be 50/50
have you checked the fan
I HAVE A 2000 IMPALA ,AND MINE DID THE SAME THING.I HAD IT CHECKED AND IT WAS THE THERMOSTAT.IT WAS CLOSED,THEREFORE IT WAS NOT ALLOWING ANY COOLANT INTO MY ENGINE,SO I REPLACED IT AND NOW ITS ALL GOOD! ANOTHER POSSIBILITY IS YOUR TEMP SENSOR. HOPEFULLY THIS HELPS.
There are two separate sensors that play here. the "coolant temperature sensor" and "coolant LEVEL sensor". I suggest confirming which of these was replaced, as it is very common for them to be confused. likely you will find the coolant sensor that was replaced was the one on the engine (temperature); The LEVEL sensor is mounted either in the coolant resivoir or in the radiator. Probably just need the proper sensor replaced.
Only if the sensor is malfunctioning.
did you use the right anti-freeze or you may have a bad fan/fan switch
