You need to get an OBDII scanner. They run about $80 to $130 and you just hook them up to the diagnostic port under the steering wheel and it gives you the diagnostic code.

Having the code will do you little good, if you don't know what to do with it, or have the expensive information and expensive equipment (not to mention Know-how) to fix it.

You could also go to Auto Zone and have them check the codes for free. That way when you take it in to the shop, if they all of a sudden tell you something that didn't show up from the Auto Zone check you can question them. Remember there are some shady people out there. Not all but there are some out there.

How does a liquid thermometer show that you have a fever?

That type of thermometer has mercury in it, which is very heat sensitive. When used for taking a temperature, the heat from the body causes the mercury to rise. The amount the level of the mercury rises is determined by the body's temperature; the higher the temp, the higher the mercury rises.

Why do we need to shake the thermometer before using it?

If you have an old thermometer that has mercury, then the shaking makes all of the mercury flow to the bottom of the thermometer. Then, you can get a better reading. The current digital ones work differently. Thermometers used for taking people temperatures are a special kind that go up with heat but don't go down with cold. So you have to shake a thermometer before taking your temperature to make the reading go down below your own temperature. Then the thermometer can go up again to read your temperature.
