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.
 

#133 of 406 oxygen sensors... or catylytic convertor? by georgejung

Aug 29, 2009 (10:32 am)

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.

#137 of 406 1998 legacy and it random blinking lights by mgc98legacy

Oct 02, 2009 (7:40 pm)

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!

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.
