P1116 2010 Ford Fusion Code - Engine Coolant Temperature Sensor is Out of Self-Test Range
Quick Answer
The Engine Coolant Temperature (ECT) Sensor is a thermistor device in which resistance changes with temperature. Common causes include Low Engine Coolant Level, Faulty Engine Coolant Temperature (ECT) sensor, Engine Coolant Temperature (ECT) sensor harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1116 2010 Ford Fusion Description
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.
What are the Possible Causes of the DTC P1116 2010 Ford Fusion?
- Low Engine Coolant Level
- Faulty Engine Coolant Temperature (ECT) sensor
- Engine Coolant Temperature (ECT) sensor harness is open or shorted
- Engine Coolant Temperature (ECT) sensor electrical circuit poor connection
- Faulty Engine Coolant Thermostat
- Damaged Powertrain Control Module (PCM)
How to Fix the DTC P1116 2010 Ford Fusion?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
