P0112 is Intake Air Temperature Sensor 1 Circuit Low. I don't know what P0112C is. I am not showing it. Sometimes it can the sensor not pluged in or a bad sensor. They will be able to see it when they read the data from the scanner. If the sensor is bad it will show a default value the the ECU will set so you can drive the car ok. It does not sound like a big deal. Good luck
