Code P0108 Acura Description

The Manifold Absolute Pressure (MAP) Sensor measures the pressure or vacuum in the manifold. This measurement is converted into an electrical signal which the Powertrain Control Module (PCM) uses to monitor the engine. The MAP Sensor outputs low signal voltage at high vacuum (throttle valve closed) and high signal voltage at low vacuum (throttle valve wide open). If the signal voltage from the MAP sensor falls below or exceeds a set value for a specified time, the PCM detects a malfunction and stores a Diagnostic Trouble Code (DTC).

Frequently Asked Questions about P0108 Acura Code

1. What does the OBDII code P0108 mean on an Acura?

P0108 indicates that the Manifold Absolute Pressure (MAP) sensor circuit is experiencing a high voltage condition, which could disrupt engine performance.

2. What are the common symptoms of the P0108 code in an Acura?

Symptoms may include poor fuel economy, engine hesitation or stalling, difficulty starting, rough idle, and an illuminated check engine light.

3. What causes the P0108 code to appear on an Acura?

Common causes include a faulty MAP sensor, damaged wiring or connectors, a vacuum leak, a clogged air filter, or a malfunctioning engine control module (ECM).

4. Can a dirty air filter trigger the P0108 code on an Acura?

Yes, a clogged or dirty air filter can restrict airflow, potentially causing abnormal MAP sensor readings and triggering the P0108 code.

5. How do I diagnose the P0108 code on my Acura?

Start by inspecting the MAP sensor and its wiring for damage, checking for vacuum leaks, cleaning or replacing the air filter, and using a multimeter to test sensor voltage.

6. Is it safe to drive an Acura with the P0108 code?

Driving with the P0108 code may be unsafe as it can cause performance issues like stalling or hesitation, which could compromise safety. Itâ€™s best to address the issue promptly.

8. Can a vacuum leak cause the P0108 code on an Acura?

Yes, a vacuum leak can lead to incorrect pressure readings by the MAP sensor, resulting in the P0108 code being stored.

9. How much does it cost to fix the P0108 code on an Acura?

Repair costs vary depending on the issue but typically range from $50 to $300 for parts and labor, with MAP sensor replacement being the most common repair.

10. Can resetting the check engine light fix the P0108 code on an Acura?

Resetting the light may clear the code temporarily, but if the underlying issue isnâ€™t resolved, the code will likely return. Proper diagnosis and repair are necessary.
