OBD II Fault Code

  • OBD II P010A

    OBD-II Code Decreased engine performance is defined as a Mass or Volume Air Flow "B" Circuit

    The Mass Airflow Sensor (MAF) measures the amount of air entering the engine. The engine control module (PCM) uses this information to determine how much fuel to use to keep the engine running properly. When the PCM detects a problem with this sensor or the circuit for the sensor, it will set code P010A.

    Decreased engine performance Symptoms

    • Decreased engine performance
    • Increased fuel consumption

    Common Problems That Trigger the P010A Code

    • Intake manifold leak
    • Mass Air Flow (MAF) sensor failure
    • Powertrain Control Module (PCM) failure
    • Wiring issue

    Common Repairs Needed for the P010A Code
