Mercedes code P0107 relates to a Manifold Absolute Pressure (MAP) sensor circuit low input.

OBD code P0107 for Mercedes indicates an issue with the Manifold Absolute Pressure (MAP) sensor circuit low input.

This means that the ECM has detected a lower than expected voltage signal from the MAP sensor.

The MAP sensor measures the intake manifold pressure, providing crucial data for fuel delivery and ignition timing.

When the voltage signal is too low, it can lead to drivability issues like rough idling, poor acceleration, or even stalling.

The ECM triggers this code based on the input it receives from the MAP sensor circuit.

Detailed information on diagnosing and repairing fault code P0107 in Mercedes vehicles.

OBDII code P0107 on a Mercedes indicates an issue with the Manifold Absolute Pressure (MAP) sensor circuit low voltage.

To diagnose, use a voltmeter to check the sensor’s voltage supply and ground.

Ensure the sensor is receiving proper voltage.

Scan tools can help monitor sensor data and confirm if the sensor is functioning correctly.

Visually inspect the wiring harness and connectors for any damage, corrosion, or loose connections.

Check for broken, bent, or pushed out pins.

If no visible issues are found, consider replacing the MAP sensor.

Remember to clear the code after repairs are made to see if the issue is resolved.
