P0107 GMC Code - Manifold Absolute Pressure/Barometric Pressure Circuit Low Input

Quick Answer

The P0107 diagnostic trouble code (DTC) for GMC vehicles indicates a low input signal from the Manifold Absolute Pressure (MAP) sensor or Barometric Pressure (BARO) sensor circuit. Common causes include Faulty MAP sensor or BARO sensor, Wiring or connector issues in the sensor circuit, Vacuum leaks in the intake system. 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 GMC Description

The P0107 diagnostic trouble code (DTC) for GMC vehicles indicates a low input signal from the Manifold Absolute Pressure (MAP) sensor or Barometric Pressure (BARO) sensor circuit. The MAP sensor measures the intake manifold pressure, while the BARO sensor measures the atmospheric pressure outside the engine. Both sensors play a crucial role in determining the air/fuel mixture and ignition timing for optimal engine performance. A low input signal can lead to incorrect fuel delivery, timing, and overall engine performance.
