Low on Coolant Defective sensor? Sensor not connected when radiator installed? If none of these are true try disconnecting battery for 10 mins. to see if this resets sensor
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.
My low coolant light remains on eventhough I have filled the ressovor. what can I do?Found after removing and replacing the sensor and bottle still had error, finally drained radiator and added correct coolant mixture in radiator, indicator went away. Appear I had a weak mixture of coolant and water in radiator, which kept giving me the "ENGINE COOLANT LOW' I guess it really was low in coolantRead more: Why_does_your_jaguar_XJ8_say_engine_coolant_low_when_it_is_full
Well, the common cause for the light coming on is the radiator is low of coolant. But I assume you have checked the coolant level and it is ok. That being the case more than likely the coolant level sensor is defective and needs replacing. Can also be the problem is in the wiring.
Heater core (radiator) needs to be cleaned or changed
Check coolant level in coolant recovery tank and radiator
In the radiator there is a sensor about 1/3rd of the way down from the top with 1 wire connected to it. When the sensor goes bad the low coolant light stays on. On our GM products replacing the sensor in the radiator turns the light off. The wire from the sensor to the dash light could have a bare spot in it and be touching metal witch would turn it on but I have never seen that yet. It would pay to check this also.
Low coolant in coolant recovery tank or radiator or defective sensor
The yellow radiator light on your Honda Accord is an indicator of low coolant in the radiator. The red radiator warning light is an indication of the engine overheating.
There is a low level sensor in the side of the radiator. They do go bad.
it looks like a radiator with coolant in! it should be red.
If it is the low coolant light, it may mean your coolant is low. If it is not low, it may be the low coolant light sensor malfunctioning.
Coolant leak possibly no fluid in radiator, hence the picture of a radiator.
