Recently i notice my fan are running at what i assume is full speed all the time, even though my car is running at normal running temp. I live in Florida and its been about 90-98 with the index hitting 109. I just changed my water pump about 2000 miles ago. Could there be a sensor not working correctly?

Usually evidence of a bad water pump or pump blockage.
Clear faults and when it happens again see if it stores a fault for pump blockage when the pump fails pieces of the motor get sent I to the coolant.. You could have one of those pieces floating around again

How many miles on the water pump? Over 40k on the pump? Go ahead and order one!
