OBD II Fault Code

  • OBD II P006C

    OBD-II Code Decreased engine performance is defined as a MAP - Turbocharger/Supercharger Inlet Pressure Correlation

    The Manifold Absolute Pressure (MAP) Sensor tells the engine control module (PCM) how much pressure is in the engine manifold. The Turbocharger Inlet Pressure Sensor tells the PCM how much pressure is going into the Turbo. The control module compares the two sensors to determine if one of the sensors has lost its calibration. If the PCM determines there is a calibration issue with one or both of the sensors, the PCM will set code P006C.

    Decreased engine performance Symptoms

    • Decreased engine performance
    • Decreased engine performance

    Common Problems That Trigger the P006C Code

    • Manifold Absolute Pressure (MAP) sensor failure
    • Powertrain Control Module (PCM) failure
    • Turbo inlet pressure sensor failure
    • Vacuum leak
    • Wiring issue
