Howzit Guys,
scratching my head and trying to trouble shoot over here. Changed the thermostat on my f90 today and now my engine warning indicator light is blinking. When I hold mode on my tach to get a code I receive the code 15 which is incorrect temperature sensor signal. I double checked to make sure it was the correct thermostat part number and it is. Even when I replace old thermostat I receive the same code and the blinking warning indicator. Even swapped the thermosensor but still has blinking warning indicator. Engine starts up fine and runs good but definitley has a harder time starting when warm. Any help greatly appreciated . Thank you
