What does Error Code P0107 mean?
Moderate Issue
DTC Code P0107 indicates a low input from the Manifold Absolute Pressure (MAP) sensor circuit, suggesting that the sensor voltage is below 0.15 V for more than 13 ms. This affects the ECM's ability to accurately measure intake manifold pressure, which is crucial for engine performance and efficiency.
What are the symptoms of Error Code P0107?
- Engine Light ON: The check engine light or service engine soon warning light illuminates, indicating a problem with the manifold absolute pressure (MAP) sensor circuit.
- Engine Rough Idle: The engine may experience a rough idle due to incorrect air-fuel mixture caused by low input from the MAP sensor.
- Engine Hesitation: There may be noticeable hesitation during acceleration as the engine struggles to adjust to the incorrect pressure readings from the MAP sensor.
What causes Error Code P0107?
- The Manifold Absolute Pressure (MAP) Sensor may be malfunctioning, leading to incorrect pressure readings.
- An open or shorted harness in the MAP Sensor can disrupt the signal transmission, causing low input readings.
- Poor electrical connections in the MAP Sensor circuit can result in intermittent or weak signals.
- A faulty Engine Control Module (ECM) might misinterpret sensor data, leading to erroneous pressure readings.

How to fix Error Code P0107?
- Verify DTC Code: Ensure the DTC P0107 is active by using an OBD-II scanner. Clear the code and perform a test drive to see if it reappears.
- Inspect MAP Sensor: Visually inspect the Manifold Absolute Pressure (MAP) sensor for any signs of damage, corrosion, or loose connections. Ensure the sensor is properly mounted.
- Check Electrical Connections: Examine the wiring and connectors leading to the MAP sensor for any signs of wear, fraying, or disconnection. Repair or replace as necessary.
- Test MAP Sensor Voltage: Using a multimeter, measure the voltage at the MAP sensor connector. The voltage should be within the manufacturer's specified range. A low voltage reading indicates a potential issue.
- Inspect Vacuum Lines: Check for any vacuum leaks or blockages in the lines connected to the MAP sensor. Ensure all hoses are intact and properly connected.
- Evaluate ECM Functionality: If all other components are functioning correctly, consider testing the Engine Control Module (ECM) for faults, as it may not be processing the MAP sensor data correctly.
