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!

There was a new setting in MHD... was that a water pump setting or a radiator fan setting?
