P0108 RAM Code - Manifold Absolute Pressure Sensor Circuit High
Quick Answer
The P0108 diagnostic trouble code (DTC) indicates that the Manifold Absolute Pressure (MAP) sensor circuit is reading a high voltage signal. Common causes include Faulty MAP sensor, Damaged or corroded wiring/connectors, Vacuum leaks in the intake system. 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 RAM Description
The P0108 diagnostic trouble code (DTC) indicates that the Manifold Absolute Pressure (MAP) sensor circuit is reading a high voltage signal. The MAP sensor is responsible for measuring the pressure within the intake manifold and providing this information to the engine control module (ECM). This data is crucial for the ECM to calculate the air-fuel mixture and ignition timing. When the MAP sensor circuit reads a high voltage signal, it can lead to inaccurate readings and disrupt the engine's performance.
Common Causes of P0108 RAM
- Faulty MAP sensor
- Damaged or corroded wiring/connectors
- Vacuum leaks in the intake system
- ECM malfunction
- Intake manifold leaks
Symptoms of P0108 RAM
- Decreased fuel efficiency
- Engine misfires or hesitation
- Rough idling or stalling
- Check Engine Light illuminated
- Loss of power or acceleration
How to Fix P0108 RAM
- Use a diagnostic scan tool to confirm the P0108 code and pinpoint the exact cause of the issue.
- Inspect the MAP sensor, wiring, and connectors for any signs of damage or corrosion.
- Test the MAP sensor using a multimeter to check for proper voltage output.
- Replace the MAP sensor if it is found to be faulty.
- Clear the DTC and perform a test drive to ensure the issue has been resolved.
Cost to Fix P0108 RAM
The cost of repairing a P0108 code can vary depending on the specific cause of the issue. In general, replacing a MAP sensor can cost between $50 and $200, while labor costs can range from $50 to $150. Additional costs may be incurred if wiring repairs or ECM replacement are necessary. It's recommended to consult with a professional mechanic for a more accurate estimate based on the specific vehicle make and model.
