P0108 Ford Code - Manifold Absolute Pressure/Barometric Pressure Sensor High Input
Quick Answer
The P0108 diagnostic trouble code (DTC) for Ford vehicles 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 readings to the ECM, Wiring Issues: Damaged or corroded wiring connections to the sensor can disrupt the signal transmission, Vacuum Leak: A leak in the intake manifold or vacuum lines can affect the pressure readings of the 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 P0108 Ford Description
The P0108 diagnostic trouble code (DTC) for Ford vehicles indicates a high input from the Manifold Absolute Pressure (MAP) sensor or Barometric Pressure (BARO) sensor. The MAP sensor measures the pressure within the intake manifold, while the BARO sensor measures the atmospheric pressure outside the engine. This information is crucial for the engine control module (ECM) to determine the correct fuel delivery and ignition timing. A high input from these sensors can lead to incorrect fuel and timing adjustments, resulting in poor engine performance, reduced fuel efficiency, and potential drivability issues.
Common Causes of P0108 Ford
- Faulty MAP/BARO Sensor: The sensor itself may be malfunctioning, providing incorrect readings to the ECM.
- Wiring Issues: Damaged or corroded wiring connections to the sensor can disrupt the signal transmission.
- Vacuum Leak: A leak in the intake manifold or vacuum lines can affect the pressure readings of the sensor.
- ECM Malfunction: A problem with the engine control module may prevent it from interpreting sensor data correctly.
- Intake Manifold Issues: Cracks or leaks in the intake manifold can impact the pressure readings, triggering the code.
Symptoms of P0108 Ford
- 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 fuel and timing adjustments.
- Poor Fuel Efficiency: A high input from the MAP/BARO sensor can lead to inefficient fuel delivery, causing the vehicle to consume more fuel than usual.
- Engine Stalling: In severe cases, the engine may stall or have difficulty starting due to incorrect sensor readings.
- Rough Acceleration: The vehicle may exhibit jerky or uneven acceleration when driving.
How to Fix P0108 Ford
- Diagnostic Scan: Use an OBD-II scanner to retrieve the specific trouble code and confirm the high input from the MAP/BARO sensor.
- Sensor Inspection: Check the sensor for any visible damage or signs of wear. Replace the sensor if necessary.
- Wiring Check: Inspect the wiring harness for any damage or corrosion. Repair or replace any faulty connections.
- Vacuum Leak Test: Conduct a smoke test to identify any vacuum leaks in the intake manifold or lines. Repair leaks as needed.
- ECM Reset: Clear the DTC and reset the ECM to allow it to relearn the correct sensor readings.
Cost to Fix P0108 Ford
The cost of repairing a P0108 code on a Ford vehicle can vary depending on the specific model and year. Typically, the price for a new MAP/BARO sensor ranges from $50 to $150, while labor costs can be around $100 to $200. Overall, the total repair cost may range from $150 to $350, including parts and labor. It's advisable to consult a qualified mechanic or auto repair shop for an accurate estimate, as prices can differ based on location and other factors.
