Code P1115 2008 Ford Fusion Description
The P1115 code on a 2008 Ford Fusion indicates a problem with the Intake Air Temperature Sensor 2 Circuit being too high. The Intake Air Temperature Sensor (IAT) is a crucial component of the engine management system, as it measures the temperature of the incoming air to the engine. This information is used by the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. When the ECM detects that the voltage signal from the IAT Sensor 2 is higher than expected, it triggers the P1115 code.
Common Causes of P1115 2008 Ford Fusion
- Faulty Intake Air Temperature Sensor 2
- Damaged wiring or connectors in the sensor circuit
- ECM malfunction
- Intake air leaks near the sensor
- Extreme weather conditions affecting sensor readings
Symptoms of P1115 2008 Ford Fusion
- Decreased fuel efficiency
- Rough idling or stalling
- Hesitation during acceleration
- Engine misfires
- Check Engine Light illuminated
How to Fix P1115 2008 Ford Fusion
- Begin by locating the Intake Air Temperature Sensor 2, typically located near the air intake manifold.
- Inspect the sensor, wiring, and connectors for any visible damage or corrosion.
- Test the sensor using a multimeter to check for proper resistance and voltage readings.
- If the sensor is faulty, replace it with a new one and ensure proper installation.
- Clear the diagnostic trouble codes from the ECM using a scan tool and test drive the vehicle to verify that the issue has been resolved.
Cost to Fix P1115 2008 Ford Fusion
The cost of repairing a P1115 code on a 2008 Ford Fusion can vary depending on the specific cause of the issue. Typically, the price of a new Intake Air Temperature Sensor 2 ranges from $30 to $100, depending on the brand and quality. Labor costs for this repair can range from $80 to $150 per hour, with the total repair time likely taking around 1-2 hours. Therefore, the total cost of parts and labor for addressing this issue could range from $110 to $400. It is advisable to consult with a trusted mechanic or auto repair shop for a more accurate estimate based on your location and vehicle specifics.

Frequently Asked Questions about P1115 2008 Ford Fusion Code
1. What does the OBDII code P1115 mean for a 2008 Ford Fusion?
P1115 indicates a problem with the Intake Air Temperature (IAT) Sensor 2 circuit, specifically that the sensor is reporting a voltage higher than expected.
2. What are the common symptoms of P1115 in a 2008 Ford Fusion?
Symptoms include poor engine performance, reduced fuel efficiency, difficulty starting, and possible illumination of the Check Engine Light.
3. What causes the P1115 code to appear in a 2008 Ford Fusion?
Common causes include a faulty IAT sensor, damaged or corroded wiring, a loose or poor electrical connection, or a malfunctioning Powertrain Control Module (PCM).
4. How do I diagnose the P1115 code on my Ford Fusion?
Start by inspecting the IAT sensor and its wiring for damage, corrosion, or loose connections. Use a multimeter to test sensor resistance and verify the circuit voltage.
5. Where is the Intake Air Temperature Sensor 2 located on a 2008 Ford Fusion?
The IAT Sensor 2 is typically integrated into the Mass Air Flow (MAF) sensor or located near the air intake system.
6. Can I drive my 2008 Ford Fusion with a P1115 code?
While the car may still be drivable, it is not recommended as the issue could lead to poor performance, reduced fuel economy, and potential engine damage over time.
7. How can I fix the P1115 code on my Ford Fusion?
Repairs may include replacing the IAT sensor, repairing or replacing damaged wiring, cleaning electrical connectors, or reprogramming/updating the PCM if needed.
8. How much does it cost to fix the P1115 code on a 2008 Ford Fusion?
Repair costs vary, but replacing an IAT sensor typically costs between $50 and $150 for parts and labor. Additional wiring or PCM repairs may increase the cost.
9. Can a dirty air filter cause the P1115 code in a 2008 Ford Fusion?
A dirty air filter itself won’t trigger P1115, but it can contribute to airflow issues that may indirectly affect sensor readings. Replace the air filter if it’s clogged.
10. Does clearing the P1115 code with an OBDII scanner fix the problem?
Clearing the code will remove it temporarily, but the underlying issue must be diagnosed and repaired to prevent the code from returning.
