Code P0118 2006 Ford Fusion Description
The P0118 code for a 2006 Ford Fusion indicates a problem with the Engine Coolant Temperature (ECT) Sensor Circuit being too high. The ECT sensor is responsible for monitoring the temperature of the engine coolant and sending this information to the engine control module (ECM). When the sensor detects a high voltage signal, it triggers the P0118 code, indicating that the engine coolant temperature is higher than expected.
Common Causes of P0118 2006 Ford Fusion
- Faulty ECT sensor
- Wiring or connector issues in the ECT sensor circuit
- Low coolant levels
- Cooling system problems, such as a stuck thermostat
- ECM failure
Symptoms of P0118 2006 Ford Fusion
- Engine overheating
- Poor fuel economy
- Rough idling
- Check Engine Light illuminated
- Inaccurate temperature gauge readings
How to Fix P0118 2006 Ford Fusion
- Begin by diagnosing the issue with a scan tool to confirm the P0118 code.
- Check the ECT sensor for any visible signs of damage or corrosion and test its resistance.
- Inspect the wiring and connectors in the ECT sensor circuit for any frayed wires or loose connections.
- Test the coolant levels and the functionality of the thermostat to ensure proper cooling system operation.
- Replace the ECT sensor if faulty and repair any wiring or connector issues as needed.
Cost to Fix P0118 2006 Ford Fusion

Frequently Asked Questions about P0118 2006 Ford Fusion Code
What does OBDII code P0118 indicate on a 2006 Ford Fusion?
Code P0118 indicates that the Engine Coolant Temperature (ECT) sensor circuit is sending a higher voltage signal than expected to the engine control module (ECM), suggesting that the coolant temperature is abnormally low.
What are common symptoms of code P0118 in a 2006 Ford Fusion?
Symptoms may include poor fuel economy, irregular temperature gauge readings, engine overheating warning, rough idling, and difficulty starting the engine.
What causes the P0118 code in a 2006 Ford Fusion?
Common causes include a faulty ECT sensor, corrosion or damage in the ECT sensor connector, problems with the ECT sensor wiring (shorts or opens), or a problem with the engine control module itself.
How can I troubleshoot the P0118 code in a 2006 Ford Fusion?
Start by visually inspecting the ECT sensor and its connector for any signs of damage or corrosion. Check the wiring for breaks or short circuits. If the visual inspection doesn’t reveal any issues, consider testing the ECT sensor with a multimeter and comparing the readings with manufacturer specifications.
What are the steps to replace the ECT sensor in a 2006 Ford Fusion?
To replace the ECT sensor: 1. Disconnect the battery. 2. Locate the ECT sensor on the engine block. 3. Disconnect the sensor’s electrical connector. 4. Remove the sensor using the appropriate socket or wrench. 5. Install the new sensor, ensuring it is securely tightened. 6. Reconnect the electrical connector and the battery. 7. Start the engine to ensure the issue is resolved.
How much does it typically cost to fix the P0118 code in a 2006 Ford Fusion?
The cost to replace an ECT sensor can vary, but typically parts are between $20 and $50, with labor costing $50 to $100 depending on the mechanic’s rates and the complexity of the replacement.
Can I drive my 2006 Ford Fusion with the P0118 code active?
While you can technically still drive with the P0118 code active, it is not advisable as it can lead to engine overheating, poor performance, and increased fuel consumption. It's best to address the issue promptly to avoid potential engine damage.
Does the P0118 code affect the emissions system of a 2006 Ford Fusion?
Yes, a malfunctioning ECT sensor can affect the emissions system as it influences the air-fuel mixture and engine timing, which can lead to increased emissions. This might cause the vehicle to fail emissions tests.
