2003 Thunderbird Coolant temperature too low

[John Hayman]

My check engine light came on and I went to Autozone. They said my coolant temp is low. They said it could be the thermostat or the sensor. Any ideas or experience with this?

How well does the heater work?

Friend had a temp gauge that dropped to "bottom." Pulled over and found that bottom radiator hose had popped off and lost nearly all coolant, so no coolant/liquid was touching the sensor = low temp reading.
