Q: What does code P1117 mean?

Engine Coolant Temperature Sensor Intermittent. P1117 on Ford vehicles means the powertrain control module (PCM) has detected an intermittent signal from the engine coolant temperature (ECT) sensor circuit. The PCM expects a steady voltage from the ECT sensor that changes smoothly with coolant temperature, and an intermittent drop or spike in that signal sets this code.
