This codes stands for "coolant temperature below thermostat regulating temperature". It is set when the desired engine operating temperature is not reached in a sufficient amount of time. The powertrain control module (PCM) monitors the engine coolant temperature (ECT) to determine when this has occurred. Common causes for this code include incorrect coolant level, a failed ECT or a stuck thermostat. For more information on this code.
