What Does P0407 Code Mean?

    OBD-II Code P0407 is defined as a Exhaust Gas Recirculation Sensor "B" Circuit Low

    EGR (Exhaust Gas Recirculation) systems are used to reduce the combustion temperature, thus reducing emissions. If the engine control module (PCM) does not detect the amount of flow requested from the EGR, it will set code P0407.

    • Decreased engine performance
    • Increased fuel consumption

    Common Problems That Trigger the P0407 Code
