I Dnt know
Either low coolant level or the engine is overheating.
engine coolant
Coolant Level too low (or sensor went bad) or Engine Compartment Temp too high / engine compartment fan failure
Likely a faulty coolant temperature sensor. Change the sensor.
flashing blue means you have an electrical issues with the coolant sensor. you probably have a bad sensor that needs replacing in the coolant bottle hope that helps Phil
It means the engine may be overheating.
Because the engine is probably too hot.
Switch the ignition off and start the car again.The light will then stop flashing.
The engine coolant temperature sensor has nothing to do with the low coolant light. The low coolant sensor is mounted in the bottom of the overflow/filling reservoir by your washer fluid bottle. You will need to verify that the coolant overflow/fill bottle has coolant in it and if it does then the sensor is bad and will have to be replaced.
When mine flashes it means that the coolant level is low.
The check engine light is flashing due to a problem with the emission system. I flashing check engine light usually indicates a random engine misfire.
coolant sensor replacement need it
