OBD II Fault Code

  • OBD II P006B

    OBD-II Code Decreased engine performance is defined as a MAP - Exhaust Pressure Correlation

    The Manifold Absolute Pressure (MAP) Sensor tells the engine control module (PCM) how much pressure is in the engine manifold. The Exhaust Pressure Sensor tells the PCM the amount of pressure in the exhaust manifold. 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 P006B.

    Decreased engine performance Symptoms

    • Decreased engine performance
    • Decreased engine performance

    Common Problems That Trigger the P006B Code

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