Code P0116 2017 Ford F150 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. The 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 Sensor is located in an engine coolant passage and measures the engine coolant temperature. The PCM uses the engine coolant temperature input for fuel control and for cooling fan control. The ECT Sensor can be a threaded or twist lock type.
This Diagnostic Trouble Code (DTC) is set when the engine coolant temperature or cylinder head temperature value is higher than the calibrated value and could prevent one or more On Board Diagnostic (OBD) monitors from completing. The PCM runs this logic after an engine off and a calibrated soak period (typically 6 hours). This soak period allows the intake air temperature and the engine coolant temperature or cylinder head temperature to stabilize and not differ by greater than a calibrated value. This DTC sets when all of the following conditions are met: The engine coolant temperature at engine start exceeds the intake air temperature at engine start by greater than a calibrated value, typically 17°C (30°F), the engine coolant temperature exceeds a calibrated value, typically 107°C (225°F), the fuel system, heated oxygen and misfire monitors have not completed, snd the calibrated time to set this DTC has expired.
What are the Possible Causes of the DTC P0116 2017 Ford F150?
- Low engine coolant level
- Faulty Engine Coolant Temperature (ECT) Sensor
- Faulty engine coolant thermostat
- Engine Coolant Temperature Sensor harness is open or shorted
- Engine Coolant Temperature Sensor circuit poor electrical connection
How to Fix the DTC P0116 2017 Ford F150?
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.

Frequently Asked Questions about P0116 2017 Ford F150 Code
1. What are the common symptoms of OBDII code P0116 on a 2017 Ford F150?
The common symptoms include an illuminated Check Engine light, inaccurate temperature gauge readings, poor fuel economy, and potential issues with the engine's performance.
2. What could cause the OBDII code P0116 to trigger on a 2017 Ford F150?
The code P0116 usually indicates a problem with the Engine Coolant Temperature (ECT) Sensor 1, such as a faulty sensor, damaged wiring, or a poor electrical connection.
3. How can I diagnose the OBDII code P0116 on my 2017 Ford F150?
Diagnosing code P0116 involves checking the ECT sensor's electrical connections, inspecting the sensor for physical damage, and testing the sensor's resistance with a multimeter to determine if it is functioning properly.
4. Can a faulty thermostat cause the OBDII code P0116 on a 2017 Ford F150?
Yes, a faulty thermostat can potentially cause the ECT sensor to read out of range, triggering the P0116 code. It is advisable to inspect and test the thermostat along with the ECT sensor during diagnosis.
5. What are some repair tips for fixing the OBDII code P0116 on a 2017 Ford F150?
Repair tips include replacing a faulty ECT sensor, repairing damaged wiring or connectors, ensuring proper grounding, and checking for any coolant leaks that could affect temperature readings.
6. Is it safe to drive my 2017 Ford F150 with the OBDII code P0116 active?
It is generally not recommended to drive with the P0116 code as it can lead to poor engine performance and potential overheating issues. It's best to address the underlying problem promptly.
7. Will resetting the OBDII code P0116 on my 2017 Ford F150 make it disappear permanently?
Resetting the code may temporarily turn off the Check Engine light, but if the underlying issue causing the P0116 code is not fixed, it is likely to reappear after driving cycles as the problem persists.
8. Can a dirty or low coolant level trigger the OBDII code P0116 on a 2017 Ford F150?
Yes, a low coolant level or dirty coolant can affect the ECT sensor's readings, leading to the P0116 code. It's important to check and maintain the proper coolant level and quality.
9. How much does it typically cost to repair the OBDII code P0116 on a 2017 Ford F150?
The cost of repairing the P0116 code can vary based on the underlying cause, but it generally involves replacing the ECT sensor, which can range from $50 to $200, plus labor costs if done by a mechanic.
