Code P1115 2010 Ford Fusion Description
The P1115 diagnostic trouble code (DTC) for a 2010 Ford Fusion indicates a problem with the Intake Air Temperature Sensor 2 Circuit High. This sensor is responsible for measuring the temperature of the air entering the engine. The Engine Control Module (ECM) uses this data to adjust the air-fuel mixture for optimal combustion. When the ECM detects a high voltage signal from the Intake Air Temperature Sensor 2, it triggers the P1115 code.
Common Causes of P1115 2010 Ford Fusion
- Faulty Intake Air Temperature Sensor 2: The sensor itself may be malfunctioning, providing incorrect temperature readings to the ECM.
- Wiring Issues: Damaged or corroded wiring in the sensor circuit can cause a high voltage signal to be sent to the ECM.
- ECM Malfunction: A problem with the Engine Control Module can also trigger the P1115 code.
- Intake Air Leaks: Air leaks in the intake system can affect the temperature readings of the sensor, leading to the code.
Symptoms of P1115 2010 Ford Fusion
- Check Engine Light: The most common symptom associated with the P1115 code is the illumination of the Check Engine Light on the dashboard.
- Reduced Fuel Efficiency: A faulty Intake Air Temperature Sensor 2 can lead to incorrect fuel injection, resulting in decreased fuel efficiency.
- Rough Idle: The engine may experience rough idling or hesitation when the air-fuel mixture is not properly adjusted.
- Engine Misfires: Incorrect air temperature readings can cause the engine to misfire, leading to a rough running engine.
- Lack of Power: The vehicle may lack power during acceleration due to improper fuel injection timing.
How to Fix P1115 2010 Ford Fusion
- Diagnose the Issue: Use a scan tool to retrieve the DTC and perform a thorough inspection of the Intake Air Temperature Sensor 2 and its wiring.
- Replace the Sensor: If the sensor is found to be faulty, replace it with a new one following the manufacturer's guidelines.
- Repair Wiring: If wiring issues are detected, repair or replace the damaged wires to ensure proper connectivity.
- Clear DTC: After completing the repair, clear the DTC from the ECM memory using a scan tool to reset the Check Engine Light.
- Test Drive: Take the vehicle for a test drive to ensure that the issue has been resolved and that the engine is running smoothly.
Cost to Fix P1115 2010 Ford Fusion
The typical repair costs for addressing the P1115 code on a 2010 Ford Fusion can range from $100 to $300, depending on the specific cause of the issue and the cost of parts and labor in your area.
