    When I replaced the sensor I added coolant to the bottle but I did not run the engine until my wife went to work the next day. Could that be the cause of the light coming that the coolant in the bottle went to the radiator.

Is there coolant in the system ? if there is go to the coolant bottle there is a sensor in the bottom of that bottle if there is any thing beside coolant in that bottle it will cause the sensor to act erraticly. if there is no coolant our low coolant then the sensor is working you need to look for a leak

Yes, this is very important maintenance procedures. Transmission should be serviced (filter, oil, and oil pan gasket replaced) @ 60K miles, plugs at 100K miles (I'd replace them early for better gas mileage), and radiator flushed @ 60K miles. Hopefully this helps!!
