OBD-II DTC P0107 – Manifold Absolute Pressure/Barometric Pressure Circuit Low Input
DTC P0107 meaning
DTC P0107 refers to a diagnostic trouble code that indicates a low input signal from the Manifold Absolute Pressure (MAP) sensor or the Barometric Pressure sensor. This code is triggered when the Engine Control Module (ECM) detects that the voltage signal from the MAP sensor is below the expected range, suggesting a potential issue with the sensor or its circuit.
DTC P0107 symptoms
Common symptoms associated with DTC P0107 may include:
- Check Engine Light illuminated
- Reduced engine performance
- Rough idling or stalling
- Poor fuel economy
- Difficulty starting the engine
DTC P0107 causes
Several factors can lead to the triggering of DTC P0107, including:
- Faulty MAP sensor
- Wiring issues such as shorts or open circuits
- Corroded or loose electrical connectors
- Vacuum leaks in the intake system
- Faulty Barometric Pressure sensor
DTC P0107 seriousness
DTC P0107 is considered a moderate to serious issue. While the vehicle may still be operable, the low input signal can lead to poor engine performance, increased emissions, and potential long-term damage if not addressed. It is advisable to diagnose and repair the issue promptly to avoid further complications.
How to diagnose DTC P0107
To diagnose DTC P0107, follow these steps:
- Use an OBD-II scanner to confirm the presence of the code.
- Inspect the MAP sensor and its wiring for any visible damage or disconnections.
- Check the voltage output of the MAP sensor with a multimeter.
- Test for vacuum leaks in the intake system.
- Clear the code and perform a road test to see if the code returns.
