P0106 Subaru 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 Subaru 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 Subaru?
- 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 Subaru Code
1. What does the OBDII code P0106 mean on a Subaru?
P0106 indicates a problem with the Manifold Absolute Pressure (MAP) sensor, specifically that its signal is out of range or inconsistent with expected engine performance.
2. What are the symptoms of a P0106 code in a Subaru?
Symptoms may include poor fuel efficiency, rough idling, stalling, hesitation during acceleration, and the check engine light turning on.
3. What causes the P0106 code to appear on a Subaru?
Common causes include a faulty MAP sensor, vacuum leaks, clogged air filters, damaged wiring or connectors, and issues with the engine control module (ECM).
4. Can a dirty air filter trigger the P0106 code in a Subaru?
Yes, a clogged air filter can restrict airflow, leading to inaccurate MAP sensor readings and triggering the P0106 code.
5. How do you diagnose a P0106 code on a Subaru?
Diagnosis typically involves inspecting the MAP sensor, checking for vacuum leaks, testing the sensor’s voltage with a multimeter, and examining related wiring and connectors.
6. Is it safe to drive with a P0106 code on a Subaru?
While the car may still be drivable, it can experience reduced performance and fuel efficiency. Prolonged driving without repairs may cause further engine damage.
7. How do you fix a P0106 code on a Subaru?
Repairs may include replacing the MAP sensor, fixing vacuum leaks, cleaning or replacing the air filter, repairing damaged wiring, or updating the ECM software.
8. Will clearing the P0106 code solve the problem permanently?
Clearing the code will turn off the check engine light temporarily, but the issue will likely return unless the underlying problem is resolved.
9. Can a vacuum leak cause the P0106 code on a Subaru?
Yes, a vacuum leak can disrupt the MAP sensor's ability to measure pressure accurately, triggering the P0106 code.
10. How much does it cost to fix a P0106 code on a Subaru?
Repair costs can vary depending on the cause, ranging from $50 for a simple air filter replacement to $300 or more for a new MAP sensor or wiring repairs.
