Code Definition

P2007 — Manifold Air Pressure Signal Fault

System: Powertrain  |  Type: Generic (OBD-II Standard)  |  Make: Mercedes-Benz

About P2007

P2007 is a generic (obd-ii standard) powertrain diagnostic trouble code recorded for Mercedes-Benz vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

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 P2007 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 Engine Control Module (ECM) sets this code when it detects an implausible or out-of-range signal from the Manifold Absolute Pressure (MAP) sensor. The MAP sensor monitors intake manifold pressure and provides data for fuel injection and ignition timing adjustments. A signal fault can occur due to an electrical issue or sensor malfunction, leading to incorrect air-fuel mixture calculations.
