Subaru Legacy/Outback "Check Engine" Light Problems

    Thanks for the tip....yes, it's been reset, but when it is ocurring during the inspection timeframe, you have to drive it some miles before the computer will accept the inspection. In NYS we have an annual inspection. What I'm really concerned about is the safety issue as there is a slight odor of fuel inside the car. We've had 2 smoke tests and using those results done those repairs to no avail. Everything's been tightened and closely inspected for cracks, leaking fuel, etc. It seems to come back on when I go on a longer trip than usual....over 50 miles or so. Just going back and forth to town (12 miles each way) doesn't seem to do it.

    Could be as simple as a bad bulb. Not easy to access, unfortunately.

    Search on Scoobymods to see if anyone has instructions for taking the dash apart. Your problem is way too specific to find someone who can answer you.

    perhaps someone disabled it on purpose (like to sell the car to an unsuspecting buyer).

    I know this thread is ancient, but I had to make a comment.
    The 1995 Subaru IS OBD-II compliant.
    Obviously the Person at Advance isnt aware that some cars made prior to 1996 (the official year ALL manufactures had to be OBD-II compliant) were OBD-II compliant before that mandatory year.
    Seeings how I myself own a 95 Subaru Legacy, and own a OBD-II reader, I can vouch that it indeed is OBD-II compliant.
    If you see the person again at Advance (provided this person is still working there) and tell them of this fact.
    Giving bad info to customers is a good way to make things way harder than they should be.
    Coming from an Autoparts store as a manager for 7 years, these kind of mistakes happen all the time with all the changes made.
    Small and large.

  • I've posted earlier on this thread.... then got side tracked. My 05 Legacy had a CEL several months ago - $300 later, had a new 'post convertor' sensor on, and all is well... for two weeks, when it happened again. After discussing it here, I took it to an Advance Auto Parts store, where they kindly did an OBDII scan - got the codes as follows.

    P0131
    O2 sensor
    Circuit Low volts
    (Bank 1 Sensor 1)

    and

    P2097
    Post Catalyst
    'fuel Trim Bank 1
    System too Rich

    I read a manual - found the 'upstream' sensor and harness - difficult lil' bugger to reach. What I'm wondering now - is it the sensor ? Or is my cat convertor shot? It only has 21,000 miles on it. Any tips greatly appreciated!
  • My '03 Legasy has set a P0507. I have already cleaned the throttle body and IAC. The CEL is on intermitantly now. I have never seen the idle speed hang too high. I priced an IAC at $300 ouch! Is there anything else that will set that code? I have checked for vacuum leaks, none, fuel trims are at 0 long and short, and I've checked for throttle cable misadjustment all ok. The car runs perfect and only has 63000 miles.It is a manual trans car by the way.

    I have gotten this code - well so many times that I cannot count - over the past 5 to 7 years on my 2001 Legacy wagon. I am not willing to spend the money to get a new Cat system, so I tried putting in a fuel line cleaner in. About a half a tank later it went off. I went to a different gas station and it was fine, but when I went back to the place that I filled up prior to the first time the light was back on after a quarter of a tank same code. So it seems to me, atleast with my car, it is quality of fuel.
  • i had the same problem with my nissan xterra 2003. 2 codes P0328/P0420. already got knock sensor replaced. now the check engine light is back. really hate to pay 2k more to replace catalytic converter. i will check what's the current code.
  • new to the forum, anyways i've got a 2.5 GT 1998 legacy that just recently began having the hazard lights, the dashboard, radio all start blinking when the car is off. I noticed that while this off the same clicking noise it makes off is also occuring while the car is running. the check engine light had been on, i had recently changed all the spark plugs, spark plug wire, and cooling system. The car runs fine with the check engine light on. I feel this is something to do with another aspect of the electronics system. any ideas??? i pulled the battery and put her to sleep for the night. thanks for any help!
  • to clarify post #137 the check engine light is off now that everything is blinking. sorry, thanks

    I wonder if it could be an alarm or remote keyless system malfunction? Change the battery on the key fob, perhaps?

    If you've still got te 2005 XT - you need to be very careful about the turbo. I have a 2005 Outback XT with 67K. I've been very good about changing oil and my turbo has now blown out. It's been in the shop for the last few days and I don't have a complete diagnosis yet, but I'm sure that it will be very expensive. Apparently there is a mesh screen in the banjo bolt that's in the turbo clogs and starves the engine of oil and bang - you've got a dead turbo on your hands. Looks like Subaru knows about the problem but hasn't been informing it's owners. Maybe this screen can be cleaned - if so it will save you much hassle. Just wanted you to be aware. I'll probably be posting more about my situation soon. :sick:

    I think peaty has a mod for that on scoobymods, FWIW.
  • This car has about 50,000 miles and I have owned it since new and had it dealer maintained. The CEL came on recently, and apart from now running rough for a few minutes when starting from cold it runs reasonably well. I take it into the dealer on Nov. 6, and having read all the horror stories about trial and error part replacement in order to get the light turned off, does anyone have advice as to how I can avoid this happening to me.

    Any ideas as to what may be the problem.
