I believe the sensor could still be bad. How? .... pull the plug on the top of the sensor. Then look inside the top of the sensor where the contacts are.... is there coolant in there? If there is then the expansion tank could possibly go dry but the coolant inside the plug connection could fool the system by allowing current to pass through this small amount of coolant from one of the contacts to the other.... If it's wet in there replace the coolant level sensor or risk having a sensor that will not register low coolant. Bill |
