About P00C7

P00C7 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 P00C7 is stored, the module has detected a correlation fault — two sensors that should track each other have diverged beyond tolerance; a bank-specific fault, meaning it applies only to one cylinder bank of a multi-bank engine; and a sensor-related fault — the reported value from the named sensor is out of spec.

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 P00C7 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

DTC P00C7 indicates a correlation fault between the multiple intake air pressure measurement sensors used by the Engine Control Module (ECM) on Bank 1. Most modern engines use a Manifold Absolute Pressure (MAP) sensor, a Barometric Pressure (BARO) sensor, and often a Mass Air Flow (MAF) sensor working together so the ECM can calculate engine load, fuel quantity, and ignition timing. The ECM continuously cross-checks these inputs against each other and against modelled expected values — for example, with the engine off and key on, the MAP and BARO readings should match (both reading atmospher...
