I have P1112 (Engine Coolant Temperature Radiator Outlet Sensor, High Input) fault code that will not stay cleared. My check coolant caution came on, I opened the top, poured in about half a liter of coolant. BOOM. Service Engine Soon came on after restarting. The code is the 1112. It will clear and stay cleared, until the vehicle is restarted. Any help is greatly appreciated.
