P0106 Mitsubishi Code - Manifold Absolute Pressure Circuit Range/Performance Condition
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 P0106 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 determines the MAP Sensor is stuck within the normal operating range. It accomplishes this by running 3 different models within the software to determine the values.
What are the Possible Causes of the DTC P0106 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 P0106 Mitsubishi Code
1. What does the OBDII code P0106 mean for a Mitsubishi?
The P0106 code indicates a "Manifold Absolute Pressure (MAP) Circuit Range/Performance Condition," meaning the MAP sensor readings are outside the expected range compared to engine load and RPM.
2. What are the common symptoms of the P0106 code in a Mitsubishi?
Symptoms may include poor fuel efficiency, rough idling, engine stalling, hesitation during acceleration, and an illuminated check engine light.
3. What causes the P0106 code in a Mitsubishi?
Common causes include a faulty MAP sensor, vacuum leaks, clogged or damaged intake manifold, wiring or connector issues, or a malfunctioning throttle body.
4. Can a dirty air filter trigger the P0106 code in a Mitsubishi?
While uncommon, a severely clogged air filter can affect airflow and potentially contribute to issues that trigger the P0106 code.
5. How do I diagnose the P0106 code in my Mitsubishi?
Start by inspecting the MAP sensor, wiring, and connectors for damage. Use a scan tool to check for related codes and compare MAP sensor readings to expected values under different engine conditions.
6. Can I drive my Mitsubishi with the P0106 code?
Driving with the P0106 code is not recommended, as it can cause poor engine performance, reduced fuel efficiency, and potential long-term damage if the issue is not addressed.
7. How do I fix the P0106 code on my Mitsubishi?
Repairs may include replacing the MAP sensor, fixing vacuum leaks, cleaning or replacing the throttle body, or repairing faulty wiring and connectors.
8. Is the P0106 code expensive to repair on a Mitsubishi?
Repair costs depend on the cause. Replacing a MAP sensor typically costs $100–$300, while fixing wiring or vacuum leaks may vary widely depending on labor and parts.
9. Can a software update resolve the P0106 code in a Mitsubishi?
In some cases, a Mitsubishi ECU software update may resolve the issue if the code is caused by incorrect sensor calibration or programming errors.
10. How can I prevent the P0106 code from recurring in my Mitsubishi?
Regular maintenance, such as inspecting sensors, replacing air filters, and ensuring the intake system and vacuum lines are in good condition, can help prevent this code.
