P0107 Subaru Code - Manifold Absolute Pressure/Barometric Pressure Circuit Low Input
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 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 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 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)

- Common symptoms include reduced engine performance, rough idling, stalling, and potentially decreased fuel efficiency.
2. What does the OBDII code P0107 in a Subaru indicate?
- The code indicates a low input in the Manifold Absolute Pressure (MAP) or Barometric Pressure (BARO) circuit.
3. What are the possible causes of OBDII code P0107 in a Subaru?
- Possible causes include a faulty MAP sensor, damaged wiring or connectors in the circuit, vacuum leaks, or a defective Engine Control Module (ECM).
4. How can I diagnose the cause of OBDII code P0107 in my Subaru?
- Diagnose the issue by checking the MAP sensor's wiring and connectors, inspecting for vacuum leaks, testing the sensor's voltage, and scanning the ECM for any related faults.
5. Can a dirty air filter trigger OBDII code P0107 in a Subaru?
- Yes, a dirty air filter can restrict airflow to the MAP sensor, leading to incorrect readings and potentially triggering the P0107 code.
6. Is it safe to continue driving with OBDII code P0107 in my Subaru?
- It is not recommended to drive with this code present, as it can cause further damage to the engine and negatively impact performance.
7. How can I reset OBDII code P0107 in my Subaru?
- To reset the code, you can use an OBDII scanner to clear the fault codes after addressing the underlying issue causing the P0107 code.
8. What are some repair tips for fixing OBDII code P0107 in a Subaru?
- Repair tips include checking and replacing the MAP sensor if faulty, repairing any damaged wiring, fixing vacuum leaks, and ensuring proper sensor connections.
9. Can extreme weather conditions trigger OBDII code P0107 in a Subaru?
- Yes, extreme weather conditions such as very low temperatures can affect the sensor readings and potentially trigger the P0107 code.
10. How much does it typically cost to repair OBDII code P0107 in a Subaru?
- The cost of repair can vary depending on the specific cause of the issue, but it may range from $100 to $300 for parts and labor.
