P0108 2007 Ford Fusion Code - Manifold Absolute Pressure/Barometric Pressure Sensor High Input
Quick Answer
The P0108 diagnostic trouble code (DTC) for a 2007 Ford Fusion indicates a high input from the Manifold Absolute Pressure (MAP) sensor or Barometric Pressure (BARO) sensor. Common causes include Faulty MAP/BARO Sensor: The sensor itself may be malfunctioning, providing incorrect pressure readings to the ECM, Wiring Issues: Damaged or corroded wiring connections to the sensor can cause high input readings, Vacuum Leak: A leak in the intake manifold or vacuum lines can affect pressure readings and trigger this code. 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 P0108 2007 Ford Fusion Description
The P0108 diagnostic trouble code (DTC) for a 2007 Ford Fusion indicates a high input from the Manifold Absolute Pressure (MAP) sensor or Barometric Pressure (BARO) sensor. The MAP sensor measures the pressure inside the intake manifold, while the BARO sensor measures the atmospheric pressure outside the vehicle. These sensors provide crucial data to the engine control module (ECM) to calculate air/fuel mixture, ignition timing, and other engine functions.
Common Causes of P0108 2007 Ford Fusion
- Faulty MAP/BARO Sensor: The sensor itself may be malfunctioning, providing incorrect pressure readings to the ECM.
- Wiring Issues: Damaged or corroded wiring connections to the sensor can cause high input readings.
- Vacuum Leak: A leak in the intake manifold or vacuum lines can affect pressure readings and trigger this code.
- ECM Malfunction: A problem with the engine control module can also lead to erroneous sensor readings.
Symptoms of P0108 2007 Ford Fusion
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the dashboard.
- Reduced Engine Performance: The vehicle may experience a lack of power, hesitation, or rough idling due to incorrect air/fuel mixture.
- Poor Fuel Efficiency: A high input from the MAP/BARO sensor can lead to inefficient fuel delivery, resulting in decreased fuel economy.
- Stalling: In severe cases, the vehicle may stall or have difficulty starting due to incorrect engine parameters.
How to Fix P0108 2007 Ford Fusion
- Diagnose the Issue: Use a scan tool to retrieve the DTC and perform a thorough inspection of the MAP/BARO sensor, wiring, and vacuum lines.
- Replace the Sensor: If the sensor is faulty, replace it with a new OEM or high-quality aftermarket sensor.
- Repair Wiring: Repair or replace any damaged wiring connections to ensure proper sensor operation.
- Fix Vacuum Leaks: Inspect the intake manifold and vacuum lines for leaks and repair as necessary.
- Clear Codes and Test: Clear the DTC from the ECM memory, start the vehicle, and ensure that the issue has been resolved.
Cost to Fix P0108 2007 Ford Fusion
The typical repair costs for addressing a P0108 code on a 2007 Ford Fusion can range from $100 to $300, including parts and labor. However, specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. It's advisable to check local rates for a more precise estimate. Keep in mind that additional costs may apply if other components need replacement or further diagnosis is required.
