P0118 2019 Ford F150 Code - Engine Coolant Temperature Sensor 1 Circuit High
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, Faulty engine coolant thermostat. 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 P0118 2019 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 ECT Sensor signal is greater than the self-test maximum. The ECT Sensor signal maximum is -50° C (-58° F).
What are the Possible Causes of the DTC P0118 2019 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 P0118 2019 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.

The common symptoms include the engine running hot or cold, poor fuel economy, a decrease in engine performance, and potential issues with the vehicle's heating system.
2. What can cause the OBDII code P0118 to trigger in a 2019 Ford F150?
The code P0118 is typically triggered by a malfunctioning engine coolant temperature sensor, wiring issues in the sensor circuit, or problems with the engine control module.
3. How can I diagnose the OBDII code P0118 in my 2019 Ford F150?
You can diagnose the code P0118 by checking the engine coolant level, inspecting the coolant temperature sensor and its wiring for any damage, and using an OBDII scanner to read the code and sensor data.
4. Is it safe to drive my 2019 Ford F150 with the OBDII code P0118 active?
It is not recommended to drive the vehicle with the code P0118 active, as it can lead to engine overheating, potential damage to engine components, and reduced overall performance.
5. Can I repair the OBDII code P0118 in my 2019 Ford F150 myself?
If you have experience with automotive repairs and diagnostics, you may be able to replace the engine coolant temperature sensor yourself. However, it is recommended to consult a professional mechanic for accurate diagnosis and repair.
6. How much does it cost to repair the OBDII code P0118 in a 2019 Ford F150?
The cost of repairing the code P0118 can vary depending on the underlying issue. Replacing the engine coolant temperature sensor may cost between $50 to $200, including parts and labor.
7. Will resetting the OBDII code P0118 in my 2019 Ford F150 make it go away permanently?
Simply resetting the code may temporarily clear the warning light, but if the underlying issue with the engine coolant temperature sensor or circuit is not addressed, the code is likely to reappear.
8. Can a faulty engine coolant temperature sensor cause other problems in my 2019 Ford F150?
Yes, a faulty engine coolant temperature sensor can lead to issues such as inaccurate temperature readings, incorrect fuel mixture, improper engine timing, and overall poor engine performance.
9. How long does it take to replace the engine coolant temperature sensor in a 2019 Ford F150?
Replacing the engine coolant temperature sensor in a 2019 Ford F150 typically takes about 30 minutes to an hour, depending on the accessibility of the sensor and the skill level of the person performing the replacement.
10. Is the engine coolant temperature sensor the same as the thermostat in a 2019 Ford F150?
No, the engine coolant temperature sensor and the thermostat are two separate components in a vehicle. The sensor measures the coolant temperature, while the thermostat regulates the flow of coolant through the engine.
