What Does P0069 Code Mean?

    OBD-II Code P0069 is defined as a Manifold Absolute Pressure - Barometric Pressure Correlation

    The Manifold Absolute Pressure (MAP) Sensor tells the engine control module (PCM) how much pressure is in the engine manifold. The Barometric Pressure Sensor (usually built into the Mass Airflow Sensor) tells the PCM the amount of boost pressure created by the turbocharger. 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 P0069.

    P0069 Symptoms

    • Decreased engine performance
    • Decreased engine performance

    Common Problems That Trigger the P0069 Code

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