About P0107

P0107 is a generic (obd-ii standard) powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P0107 is stored, the module has detected a signal or supply voltage lower than the expected operating range.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P0107 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The P0107 code indicates a low input condition in the circuit of the Manifold Absolute Pressure (MAP) sensor or the Barometric Pressure sensor. These sensors measure the pressure inside the intake manifold and the external atmospheric pressure, respectively. The Engine Control Module (ECM) uses this data to adjust fuel injection and ignition timing. A low input signal from either sensor can result in suboptimal engine performance, including poor acceleration, rough idling, and increased emissions.
