What does code P1114 mean?

P1114 · ChryslerEngine Coolant Temperature (ECT) Sensor Circuit Intermittent Low Voltage

P1114 on Chrysler vehicles means the engine computer detected an intermittent low-voltage signal from the Engine Coolant Temperature (ECT) sensor circuit. The Powertrain Control Module (PCM) expects a steady voltage that drops as coolant warms, but it saw the signal briefly drop below the normal range or cut out entirely. This is an electrical fault in the sensor or its wiring, not a confirmed sensor failure.
