maybe cuz its low on coolant
Coolant is low or a sensor malfunction.
Low coolant level.
It is possible that a check engine light on a Toyota Highlander will come on if the coolant level is low. Usually, though, there is another light that will come on that says 'low coolant' on some older Toyota's.
The coolant level sensor is bad
Either your coolant is actually low or you have a coolant sensor bad.
the low coolant light is only for radiater coolant,does not have anything to do with fuel pump!!
If coolant full could be a bad sensor
Low coolant or a defective sensor
It's a warning sign that you are low on coolant.
Because the coolant is low.
Check the coolant level and make sure that its full, and is not leaking down over time. If the system is full then the low coolant sensor is probably bad.
Defective sensor? Usually in coolant recovery trank
