Default Code P0128

Check Engine Light came on this morning so I took it to advance to read the error code. I got a P0128 Coolant Temp Below Thermostat Regulator Temp code. What causes this and how do I fix it?

The most common cause is the thermostat. However, also make sure that you aren't low on coolant.
