P0119 2007 Ford Fusion Code - Engine Coolant Temperature Sensor 1 Circuit Intermittent

Quick Answer

The P0119 diagnostic trouble code (DTC) for a 2007 Ford Fusion indicates an issue with the Engine Coolant Temperature (ECT) Sensor 1 Circuit being intermittent. Common causes include Faulty ECT Sensor: The ECT sensor itself may be malfunctioning, causing intermittent readings to be sent to the ECM, Wiring Issues: Corrosion, damage, or loose connections in the wiring harness connected to the ECT sensor can lead to intermittent circuit problems, ECM Malfunction: A malfunctioning ECM can also cause intermittent communication issues with the ECT sensor. 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 P0119 2007 Ford Fusion Description

The P0119 diagnostic trouble code (DTC) for a 2007 Ford Fusion indicates an issue with the Engine Coolant Temperature (ECT) Sensor 1 Circuit being intermittent. The ECT sensor is a crucial component of the vehicle's engine management system, as it measures the temperature of the engine coolant. This information is used by the engine control module (ECM) to adjust fuel delivery and ignition timing for optimal performance and efficiency.

Common Causes of P0119 2007 Ford Fusion

  1. Faulty ECT Sensor: The ECT sensor itself may be malfunctioning, causing intermittent readings to be sent to the ECM.
  2. Wiring Issues: Corrosion, damage, or loose connections in the wiring harness connected to the ECT sensor can lead to intermittent circuit problems.
  3. ECM Malfunction: A malfunctioning ECM can also cause intermittent communication issues with the ECT sensor.
  4. Coolant Leak: A coolant leak near the ECT sensor can affect its readings and cause intermittent circuit problems.
  5. Electrical Interference: External factors such as electromagnetic interference can disrupt the signal between the ECT sensor and the ECM.

Symptoms of P0119 2007 Ford Fusion

  1. Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the dashboard.
  2. Engine Overheating: Inaccurate temperature readings from the ECT sensor can lead to engine overheating, as the ECM may not adjust the cooling system properly.
  3. Poor Fuel Economy: Incorrect temperature data can cause the ECM to deliver the wrong amount of fuel, leading to decreased fuel efficiency.
  4. Rough Idle: The engine may experience rough idling or stalling due to incorrect fuel delivery and ignition timing.
  5. Hard Starting: A faulty ECT sensor can make it difficult to start the engine, especially in cold weather.

How to Fix P0119 2007 Ford Fusion

  1. Diagnose the Issue: Use a scan tool to retrieve the DTC and perform a visual inspection of the ECT sensor and wiring harness.
  2. Test ECT Sensor: Test the ECT sensor using a multimeter to check for proper resistance values at different temperatures.
  3. Inspect Wiring: Inspect the wiring harness for any damage, corrosion, or loose connections. Repair or replace as needed.
  4. Check Coolant Levels: Ensure that the coolant levels are adequate and there are no leaks near the ECT sensor.
  5. Clear DTC: Once the issue is resolved, clear the DTC using a scan tool to reset the check engine light.

Cost to Fix P0119 2007 Ford Fusion

The typical repair costs for addressing a P0119 code on a 2007 Ford Fusion can range from $100 to $300, depending on the specific cause of the issue and the cost of parts and labor. This estimate includes the cost of a new ECT sensor, wiring repairs, and diagnostic labor. It's important to note that labor rates at auto repair shops can vary, with hourly rates typically ranging from $80 to $150. Additionally, prices for parts can vary based on the manufacturer and quality of the component. It's recommended to consult with a trusted mechanic or repair shop for a more accurate cost estimate based on your specific situation.
