Fault code P0117 OBDII: Car stopped and won't re-start.

Hello, No worries, just check for voltage from the engine coolant temperature sensor, and see if the voltage from the ECU is in spec, and the voltage to the ECU goes up as the engine temperature increases. It will still be below the voltage from the ECU. What is happening is that the ECU is sending a signal to the coolant temperature sensor, and the temperature sensor provides resistance and sends the weaker signal back to the ECU. That is how the vehicle knows what the engine temp is, because the sensor will allow more voltage through at higher temperatures. If the signal to the sensor is correct (either 12v or 5v), and the signal leaving the sensor does not raise as the temperature raises, change the sensor. However, you may also have a wring issue, and you should make sure the current is returning to the ECU. If you need further assistance, let me know, otherwise, here is a list of certified shops in your area that can diagnose and repair your vehicle: http://repairpal.com/scion-within-10-miles-of-north-troy-vermont-05859
