Check Engine light on & Cruse Control light flashing

    Need info for a 2005 Forester XT turbo (USA).
    I drove into work this AM without a problem.
    After work, engine idled rough, had a steady check engine light,
    and flashing cruise light (flashes 1x per second), virtually no power
    at all.
    Checked oil, found it 1.5 qt low (this is the day after a long, long
    drive at freeway speeds).
    Added oil, now engine is smooth runs like it always has,(steady idle
    and normal power & accelleration), but the check engine remains on &
    cruise control light is still flashing once per second.
    Could this just be a residual indicator from the low oil? and now the
    system needs a reset to get the lights out? or ????
    Can anyone advise how to pull the codes without a meter?
    How does one reset the check engine light?
    Thanks to all in advance.

    You need to get the codes read. Autozone does it for free, they will
    give you a printout with what it means. Other auto stores may do it as

    If there's no Auto Zone around, you can purchase a code reader for a lot
    less than a dealer will charge you to read it. Just plug it in, read the
    code, look in the book that comes with it or find the code on the Net and
    you'll have an idea of what's what. You can always reset the light with one
    of these inexpensive readers and see if it comes back on. It will if there
    is a problem. I carry one in the car and have used it more on other
    people's cars than my own. It's always been right.

    The unit the dealer has can not only read codes but allow for all kinds of
    adjustments to the engine as well. They are very expensive.

    UPDATE: I went out to the garage yesterday AM to drive over to
    The car started right up, rolled out of the garage and down the
    driveway. Put the car in drive, stepped on the gas, and nothing but
    idle. Parked in front of the house and called for a tow to the dealer.
    Problem is a bad relay in the "throttle by wire" circuitry. Dealer
    said he has only ever seen 2 go bad. Part not in stock, but due in
    tomorrow. Warranty covers.

    I suspect that they may have more redundant systems that a car

    out of range. Replaced same.

    your local auto parts store will usually reset the check engine light for free, plus let you know the codes

    My 2013 forester running normal. Check engine light and flashing cruise control came on. Still running fine with warning lights on. I take it to dealership for service . FYI on my second engine due to huge oil consumption which blew first engine. Second engine failed oil consumption test. I carry oil everywhere I go due to consumption and check oil often. Subaru very aware and say nothing can be done. Main concern today is check engine light on
