Subaru: "at oil temp" (sometimes) flashes 16 times on startup

    "at oil temp" (sometimes) flashes 16 times on startup

    I have a '97 Subaru outback with ~70,000 miles on it, automatic
    transmission.

    A couple of months back I had serious oil leak problems which seem
    mainly resolved after the crankshaft seal was replaced. (I also had
    the crank pulley replaced and the timing belt was changed)

    Now I find that sometimes (but not always) when I start the car the
    "AT OIL TEMP" light flashes exactly 16 times and then goes out.

    I've not noticed any obvious problems while driving the car.

    I suppose I need to take the car to the dealer, but I'd really
    appreciate it if anyone out there has any insight into what is causing
    this apprarently intermittent problem. In particular, how urgently do
    I need to get this looked at, and could it be related to my previous
    problems and the fixes done?

    Thanks in advance,

    Henry

    Do a search on this newsgroup or call your dealer, but I believe it's
    flashing a code of what's wrong.
    Similiar to how GM works. Whatever it is you defintely want to get it
    checked out. Autozone, Pepboys
    etc. will hook a code reader to the OBDII diagnostic port for free and
    tell you if there's any
    'codes'.

    Just having my 2001 serviced for the same but my AT HOT light stays blinking
    for the entire drive. 50K and this solinoid is under powertrain warranty.

    Call dealer service dept and ask what an AT light #16 code is. Did you count
    the blinks AND pauses to get the code number correctly? ed

    I believe the 16 flashes at start up is a "generic" warning rather
    than the specific error code for a particular problem. I tried the
    magic sequence posted once before to this group that is supposed to
    make the light flash the problem code but it didn't work.

    Time to make that appointment with a mechanic...

    I took my car into the shop.
    They said the error message is coming from "duty solenoid C". Since it
    would cost about $450 to replace this, if it's the solenoid itself
    that's bad, I was wondering if this is really necessary?

    Right now the only sign of a problem is the flashing light which I can
    easily live with! Will driving with a malfunctioning "duty solenoid C"
    cause any real problems?

    If I'm not mistaken, duty solenoid C is the solenoid that controls the
    front/back torque split. If this goes, I'm pretty sure that your AT
    will just lock in a 50/50 front/rear split. The two problems I would
    see is that sometimes your transmission will start to bind if you are
    going around a tight corner (most older AWD vehicles do this anyways),
    and I think it increases the wear on the transmission.

    Turns out that replacement duty solenoids are "on back order
    nationally" according to the shop. So, they're going to stick in the
    fuse that makes it run as front wheel drive only until the part
    arrives!

    Picked up the car with the fuse in the "FWD" socket.
    Drove it to work, halfway there the "FWD" light on the dash goes out!
    Checked that the fuse is still firmly in place.
    Looks like it hasn't blown (if I'm checking it correctly).

    I don't understand this!
    Or could this also be connected to the solenoid failure?
    Another solenoid failure?

    You have a 5yr/60K powertrain... if you are withing that. If not I would go
    with the $450. Not bad, you get a trans fluid change.
    I would drive the car and see if it goes into overdrive. After 3rd gear you
    will see a 250rpm drop as it goes into trans lock. Mine died (just flashed the
    AT hot light constantly) after 48K - fixed under warranty.
    My son's GMC had a stupid motor that shifts from 2wd-4wd-FT4WS for $925 with
    tax. $525 for this stupid part with 49K on it.
