My auxiliary cooling fan often runs even when my car is cold. Reading up on the issue it appears that this would be caused by a bad coolant temperature sensor giving a reading that the coolant is very hot. However, when I hook Nissan Data Scan up to the car and look at the value being given by the sensor I can see that it's working correctly. What else can cause this?
