P0108 2010 Ford Fusion Code - Manifold Absolute Pressure/Barometric Pressure Sensor High Input
Quick Answer
The Manifold Absolute Pressure (MAP) sensor measures the pressure inside the intake manifold. Common causes include Faulty Manifold Absolute Pressure (MAP) Sensor, Manifold Absolute Pressure Sensor harness is open or shorted, Manifold Absolute Pressure Sensor circuit poor electrical connection. 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 2010 Ford Fusion Description
The MAP sensor wiring includes 3 circuits. The Engine Control Module (ECM) supplies a regulated 5 volts to the sensor on a 5 V reference circuit. The ECM supplies ground on a low reference circuit. The MAP sensor provides a signal voltage to the ECM, relative to the pressure changes, on the MAP sensor signal circuit. The ECM converts the signal voltage input to a pressure value.
Under normal operation the greatest pressure that can exist in the intake manifold is at ignition ON, engine OFF, which is equal to the BARO. The lowest manifold pressure occurs when the vehicle is idling or decelerating. The ECM monitors the MAP sensor signal for pressure outside of the normal range.
The Diagnostic Trouble Code (DTC) will be set when the ECM detects that the MAP Sensor voltage is more than 4.50 V for greater than 13 ms.
What are the Possible Causes of the DTC P0108 2010 Ford Fusion?
- Faulty Manifold Absolute Pressure (MAP) Sensor
- Manifold Absolute Pressure Sensor harness is open or shorted
- Manifold Absolute Pressure Sensor circuit poor electrical connection
- Faulty Engine Control Module (ECM)
How to Fix the DTC P0108 2010 Ford Fusion?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.

Frequently Asked Questions about P0108 2010 Ford Fusion Code
1. What does the OBDII code P0108 mean on a 2010 Ford Fusion?
P0108 indicates that the Manifold Absolute Pressure (MAP) sensor is reporting a voltage signal that is too high, suggesting a possible problem with the sensor or related systems.
2. What are the common symptoms of the P0108 code on a 2010 Ford Fusion?
Common symptoms include poor engine performance, rough idling, hesitation during acceleration, reduced fuel efficiency, and the Check Engine Light being illuminated.
3. What causes the P0108 code to appear on a 2010 Ford Fusion?
Potential causes include a faulty MAP sensor, damaged or disconnected wiring, a vacuum leak, a clogged air filter, or an issue with the engine control module (ECM).
4. Can a dirty air filter cause the P0108 code on a 2010 Ford Fusion?
Yes, a dirty or clogged air filter can restrict airflow, potentially causing inaccurate readings from the MAP sensor and triggering the P0108 code.
5. How do I diagnose the P0108 code on my 2010 Ford Fusion?
Start by inspecting the MAP sensor and its wiring for damage or loose connections. Use a scan tool to check sensor voltage and compare it to manufacturer specifications. Inspect for vacuum leaks or clogged components.
6. Is it safe to drive my 2010 Ford Fusion with a P0108 code?
While the car may still run, driving with this code can lead to poor performance and long-term engine damage if not addressed promptly.
7. How do I fix the P0108 code on a 2010 Ford Fusion?
Repairs may include replacing the MAP sensor, repairing damaged wiring, cleaning or replacing the air filter, or fixing vacuum leaks. If necessary, update or reprogram the ECM.
8. Can a faulty ECM cause the P0108 code on a 2010 Ford Fusion?
While rare, a malfunctioning ECM could cause the P0108 code if it fails to process MAP sensor data correctly.
9. How much does it cost to fix the P0108 code on a 2010 Ford Fusion?
Repair costs vary but typically range from $100 to $300, depending on whether the issue is a faulty sensor, wiring repair, or other related problems.
10. Will clearing the P0108 code with a scanner fix the issue on a 2010 Ford Fusion?
Clearing the code will turn off the Check Engine Light temporarily but won’t fix the underlying problem. The code will likely return if the issue isn’t resolved.
