That code is a coolant tempuature is not getting to full operating tempuature. First thing to check is to verify temp sensor is connected properly. This code could mean the coolant thermostat is stuck open not allowing temp to build up properly. Also coolant level should be checked to make sure it is full.
miles is correct
