P0108 2006 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 2006 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 2006 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 2006 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 2006 Ford Fusion Code
1. What does the OBDII code P0108 mean on a 2006 Ford Fusion?
P0108 indicates that the Manifold Absolute Pressure (MAP) sensor is detecting a voltage signal higher than the expected range, suggesting an issue with the MAP sensor or its circuit.
2. What are the common symptoms of code P0108 on a 2006 Ford Fusion?
Symptoms may include poor fuel efficiency, rough idling, stalling, lack of power, black smoke from the exhaust, or the engine running rich.
3. What causes code P0108 to appear on a 2006 Ford Fusion?
Common causes include a faulty MAP sensor, a vacuum leak, wiring or connector issues, a clogged intake, or a malfunctioning PCM (Powertrain Control Module).
4. Can I drive my 2006 Ford Fusion with a P0108 code?
Driving with a P0108 code is not recommended, as it can lead to poor performance, reduced fuel efficiency, and potential damage to the engine or catalytic converter if left unresolved.
5. How do I fix the P0108 code on a 2006 Ford Fusion?
Repairs may involve replacing the MAP sensor, checking and repairing wiring or connectors, fixing vacuum leaks, or cleaning the intake manifold.
6. How can I diagnose the P0108 code on my 2006 Ford Fusion?
Start by using an OBDII scanner to confirm the code, then inspect the MAP sensor, vacuum lines, electrical connections, and intake system for damage or debris.
7. How much does it cost to fix a P0108 code on a 2006 Ford Fusion?
Repair costs vary, but replacing a MAP sensor typically costs $50–$150 for the part, plus labor if done by a professional.
8. Can a dirty air filter cause a P0108 code on a 2006 Ford Fusion?
While unlikely, a severely clogged air filter could contribute to airflow issues that may indirectly affect MAP sensor readings, so it’s worth checking.
9. Will clearing the P0108 code solve the problem on my 2006 Ford Fusion?
Clearing the code won’t fix the root cause. The issue must be diagnosed and repaired to prevent the code from returning.
10. Does a P0108 code mean the MAP sensor is definitely bad?
Not necessarily. Other issues like wiring problems, vacuum leaks, or a faulty PCM can also trigger this code, so proper diagnosis is essential.
