How to Fix the DTC P1116 2009 Ford Fusion?

Review the 'Possible Causes' mentioned above and visually examine the corresponding wiring harness and connectors. Ensure to check for any damaged components and inspect the connector pins for signs of being broken, bent, pushed out, or corroded.

Code Tech Notes

Start by checking for coolant leaks, if there are not leaks the thermostat might be stuck open or closed and may need to be replaced, you still have an issue the engine coolant temp sensor or cylinder head temp sensor. The engine coolant temperature must be greater than 10°C (50°F) to pass the key ON engine OFF (KOEO) self-test and greater than 82°C (180°F) to pass the key ON engine running (KOER) self-test.

Code P1116 2009 Ford Fusion Description

The Engine Coolant Temperature (ECT) Sensor is a thermistor device in which resistance changes with temperature. The electrical resistance of a thermistor decreases as the temperature increases, and the resistance increases as the temperature decreases. The varying resistance changes the voltage drop across the sensor terminals and provides electrical signals to the Powertrain Control Module (PCM) corresponding to temperature.
Thermistor-type sensors are considered passive sensors. A passive sensor is connected to a voltage divider network so varying the resistance of the passive sensor causes a variation in total current flow. Voltage that is dropped across a fixed resistor (pull-up resister) in series with the sensor resistor determines the voltage signal at the PCM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor.
The ECT measures the temperature of the engine coolant. The PCM uses the ECT input for fuel control and for cooling fan control. There are 3 types of ECT sensors; threaded, push-in, and twist-lock. The ECT sensor is located in an engine coolant passage.
