Anyone know what code P 0117 is? Got it on way home from work.

P0117-ENGINE COOLANT TEMPERATURE SENSOR CIRCUIT LOW

Theory of Operation
The engine coolant temperature sensor is a negative temperature coefficient thermistor-type sensor whose resistance varies inversely with temperature. At cold temperatures the sensor resistance is high so the voltage is high. As the coolant temperature increases the resistance decreases and the voltage becomes low.

• When Monitored: With the ignition on. Battery voltage greater than 10.4 volts.
• Set Condition: The PCM detects that the Engine Coolant Temperature Sensor input voltage is below the minimum acceptable value. One Trip Fault. Three good trips to clear the MIL. The MIL and ETC light will illuminate if equipped.

Thanks ronjenx;
Went to the dealership and it's fixed. Best of all at no charge!!!!!
