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

Quick Answer

The P0107 code for Saturn vehicles indicates a problem with the Manifold Absolute Pressure (MAP) or Barometric Pressure (BARO) sensor circuit, specifically a low input signal being detected by the Engine Control Module (ECM). Common causes include Faulty MAP/BARO sensor, Damaged wiring or connectors in the sensor circuit, Vacuum leaks in the intake manifold. 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 Saturn Description

The P0107 code for Saturn vehicles indicates a problem with the Manifold Absolute Pressure (MAP) or Barometric Pressure (BARO) sensor circuit, specifically a low input signal being detected by the Engine Control Module (ECM). The MAP sensor measures the pressure within the intake manifold, while the BARO sensor measures the atmospheric pressure outside the engine. These sensors are crucial for the ECM to calculate the air/fuel mixture and adjust engine performance accordingly.
