OBD II Fault Code

  • OBD II P006A

    OBD-II Code Decreased engine performance is defined as a MAP - Mass or Volume Air Flow Correlation

    The Manifold Absolute Pressure (MAP) Sensor tells the engine control module (PCM) how much pressure is in the engine manifold. The Mass Airflow Sensor tells the PCM the amount of air flowing through the engine. 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 P006A.

    Decreased engine performance Symptoms

    • Decreased engine performance
    • Decreased engine performance

    Common Problems That Trigger the P006A Code

    • Manifold Absolute Pressure (MAP) sensor failure
    • Mass Air Flow (MAF) sensor failure
    • Powertrain Control Module (PCM) failure
    • Vacuum leak
    • Wiring issue
