P0107 Mitsubishi Code - Manifold Absolute Pressure Circuit Low Voltage
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 P0107 Mitsubishi 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 less than 0.15 V for greater than 13 ms.
What are the Possible Causes of the DTC P0107 Mitsubishi?
- 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)

Frequently Asked Questions about P0107 Mitsubishi Code
1. What does the OBDII code P0107 mean for a Mitsubishi?
P0107 indicates a low voltage signal from the Manifold Absolute Pressure (MAP) sensor, which measures engine vacuum or pressure to help manage air-fuel mixture and ignition timing.
2. What are the common symptoms of a P0107 code on a Mitsubishi?
Symptoms include poor engine performance, rough idling, decreased fuel efficiency, hesitation during acceleration, and possible stalling.
3. What causes the P0107 code to trigger in a Mitsubishi?
Common causes include a faulty MAP sensor, damaged wiring or connectors, a vacuum leak, or a defective Engine Control Unit (ECU).
4. Can I drive my Mitsubishi with a P0107 code?
While it may be possible to drive, it’s not recommended as the vehicle may experience severe performance issues and potential long-term engine damage.
5. How do I diagnose the P0107 code on my Mitsubishi?
Start by inspecting the MAP sensor, its wiring, and connectors for damage. Use a multimeter to test the sensor's voltage output and compare it to specifications.
6. What is the most common fix for a P0107 code on a Mitsubishi?
Replacing a faulty MAP sensor is the most common fix. However, repairing damaged wiring or connectors and addressing vacuum leaks may also resolve the issue.
7. How much does it cost to fix a P0107 code on a Mitsubishi?
The cost varies but typically ranges from $100 to $300, depending on whether the MAP sensor requires replacement or if additional repairs like fixing wiring or vacuum leaks are needed.
8. Can a dirty air filter cause a P0107 code in a Mitsubishi?
While unlikely, a severely clogged air filter can impact engine performance, but it’s not a direct cause of the P0107 code.
9. Will clearing the P0107 code with a scanner fix the issue?
Clearing the code may turn off the check engine light temporarily, but the underlying issue must be addressed to prevent the code from returning.
10. How can I prevent the P0107 code from appearing in my Mitsubishi?
Regular maintenance, including checking the MAP sensor, ensuring wiring is intact, and inspecting for vacuum leaks, can help prevent this code.
