How does the M50 coolant sensor work?
I am not sure how the coolant sensor really works. I know it is a float that drops when the coolant level is low. If low, the low coolant message is displayed.
However, when the sensor message is displayed, I think it means there is an electrical "open" vs a closed circuit with the message not displayed. Not sure?
Can someone help me understand it? I still get the message after replacing the sensor. I think itis an electrical issue and want to track it down.
Thanks
