    The check engine light came on in my Forester. I got the diagnostic
    code, PO106- manifold absolute pressure/barometric pressure circuit
    range/performance problem. The Subaru technical site had a bulletin
    concerning the air flow meter sensor.It stated that the element becomes
    contaminated with Silicon oil, Carbon and dust at the sensor base
    causing a malfunction. My question is, where is the air flow meter
    sensor located? Is this something I could access and clean? Any help
    would be appreciated. My state requires emission inspection and if the
    check engine light is not turned off it will not pass.

    The meter should be attached to the air filter box and will be upstream of
    the throttle.
