Code P0107 Cadillac Description
The P0107 diagnostic trouble code (DTC) for Cadillac vehicles indicates a low input signal from the Manifold Absolute Pressure (MAP) sensor or Barometric Pressure (BARO) sensor. The MAP sensor measures the pressure inside the intake manifold, providing crucial data to the engine control module (ECM) for fuel delivery and ignition timing. The BARO sensor, on the other hand, measures the atmospheric pressure outside the vehicle, which is used by the ECM to adjust fuel trim and optimize engine performance. A low input signal from either sensor can lead to incorrect air/fuel mixture ratios, affecting engine performance and fuel efficiency.
Common Causes of P0107 Cadillac
- Faulty MAP/BARO sensor.
- Wiring or connector issues in the sensor circuit.
- Vacuum leaks in the intake system.
- Clogged or dirty air filter.
- ECM software or hardware malfunction.
Symptoms of P0107 Cadillac
- Decreased engine performance and power.
- Rough idling or stalling.
- Poor fuel economy.

How to Fix P0107 Cadillac
- Begin by performing a visual inspection of the MAP/BARO sensor and its wiring harness for any signs of damage or corrosion.
- Test the sensor using a multimeter to check for proper voltage output.
- Inspect the intake system for any leaks or obstructions, such as a clogged air filter.
- Clear the DTC from the ECM using a scan tool and monitor sensor data while driving to ensure the issue has been resolved.
- If the problem persists, consider replacing the MAP/BARO sensor or consulting a professional technician for further diagnosis.
Cost to Fix P0107 Cadillac
