P0107 Volvo 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 Volvo 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 Volvo?
- 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)

1. What are the common symptoms of OBDII code P0107 in a Volvo?
- Common symptoms include poor engine performance, rough idling, stalling, decreased fuel efficiency, and possibly a check engine light.
2. What does the OBDII code P0107 in a Volvo indicate?
- The code P0107 indicates a low input signal from the Manifold Absolute Pressure (MAP) sensor or Barometric Pressure (BARO) sensor circuit.
3. What are the possible causes of OBDII code P0107 in a Volvo?
- Possible causes include a faulty MAP sensor, damaged wiring or connectors in the sensor circuit, vacuum leaks, or a problem with the engine's intake system.
4. How can I diagnose the OBDII code P0107 in my Volvo?
- Diagnosis typically involves checking the MAP sensor's electrical connections, inspecting for any visible damage to wiring, testing the sensor's functionality, and verifying vacuum levels in the intake system.
5. Can a dirty air filter trigger the OBDII code P0107 in a Volvo?
- Yes, a dirty air filter can disrupt the airflow to the MAP sensor, potentially causing the sensor to send incorrect readings and trigger the code P0107.
6. Is it safe to drive my Volvo with the OBDII code P0107 present?
- It is not recommended to drive with the code P0107 present, as it can lead to poor engine performance, potential stalling, and further damage to the engine if left unresolved.
7. How can I repair the OBDII code P0107 in my Volvo?
- Repairing the code P0107 involves addressing the root cause, which may include replacing the MAP sensor, repairing damaged wiring, fixing vacuum leaks, or cleaning/replacing the air filter.
8. Can a DIY enthusiast fix the OBDII code P0107 issue in a Volvo?
- Depending on the cause of the code, a DIY enthusiast with automotive knowledge and tools may be able to address the issue by following proper diagnostic procedures and repair steps.
9. Will resetting the check engine light resolve the OBDII code P0107 in a Volvo?
- Resetting the check engine light will clear the code temporarily, but if the underlying issue causing the code is not fixed, the code will likely reappear after driving the vehicle.
10. How can I prevent the OBDII code P0107 from occurring in my Volvo?
- Regular maintenance, such as replacing the air filter as recommended, checking for vacuum leaks, and ensuring proper sensor function during routine inspections, can help prevent the code P0107 from occurring.
