#170 of 406 2001 Subaru Outback with Check Engine Light
Jan 27, 2010 (11:05 am)
I'm reading through the thread, but can't find anyone with my same issue. The CEL light has been coming on most of the time over the past week. The only problem I noticed prior to this development was that my winshield wash pump no longer seems to be working well - the liquid doesn't shoot out much at all (and yes - the resevoir is full!)
Any chance these are related?
I'm planning on taking it to the dealer unless someone has a good idea that I can try at home. I'm decent with cars - but haven't run into this problem before.

I'm afraid not. OBD-II is for monitoring engine performance that impacts emissions compliance. Anything that would push the emissions to 1.5X or so of the EPA certification will log a code & trigger the light. While the manufacturer does play a role in selecting sensors and the test methodology, you can be sure that windshield washer performance was not part of the monitoring plan!
I'm constantly getting car wax into the nozzles, degrading the flow. The opening is pretty big, so try going at it with a needle or a stripped length of fine electric wire.

If it's below freezing, you may have old fluid in there that no longer has its antifreeze capability. That's happened to me before.

Thank you for the responses. I took the car to the dealer, and it was an oxygen sensor that was causing the CEL. They replaced it and its now off. Paid ~230 parts/labor
The wiper issue was plain stupid me. Ran out. I thought I had just filled it - I will check for cracks.

The OEM Oxygen Sensor is around $100 for the front, $135 for the rear. Add in an hour or so for reading the code and scoping the sensor output. Good diagnostics include making sure that this is really the cause, and not something that is simply fingering it as the cause! Change the sensor, rescope to be sure it works, then test drive and read the codes again to be sure that it hasn't logged a new pending code that will throw a CEL two days from now.
Add it up, and I'd say you are north of 2 bills!
#175 of 406 CEL Catalytic Converter
Jan 30, 2010 (11:13 am)
I have a 2002 Outback and the check engine light has been on for a couple of years now. This year, my mechanic said that it will no longer pass emissions testing and I have to resolve the issue. His code pointed to the catalytic converter, but he said that I need to have the dealer do it because he's replaced a bunch of them and the CEL comes back on. After reading the thread above, I'm reluctant to pay $1200 to replace the catalytic converter if that is not really the problem. How will I know before spending the money? And is this a common problem? Thanks.

I could write a book on this subject, but don't have time to elaborate today. Basically, I personally don't like simple code readers because they tell you little, leaving you to guess what to fix. A computer scanner gives you snapshot data of the events logged at the same time surrounding the throwing of the code. Plus OBD realtime monitoring under operating conditions (plotting RPM, load, temps, throttle position, front and rear O2 sensor output voltage, etc.) provide solid data that can pinpoint the probable cause of fault. Finally, the dealer can tap directly into the O2 sensor wiring and scope the output to confirm that the wiring back to the ECM is OK. It could be an ECM mental problem, an oxygen sensor issue, an inefficient cat, or even something as simple as a temperature sensor calibration that is allowing the system to switch from open loop to closed loop too early and logging a code before the cat is fully warmed up.
Your local mechanic is smart. Without the proper tools, he can only begin changing things and hope for the best. You'll pay more at the dealer, but they then have to warranty their work.

All things considered both issues are resolved and you spent a lot less than I expected, so call it good.

Yup, they only describe a symptom.
If the cat is going bad, it still had to be something upstream that let unburned fuel pass, which clogged up the cat. A new cat may just clog up again eventually.
#179 of 406 Thanks fibber2

Thanks fibber 2 for your response. I look forward (hopefully before too long) to your piece that you are going to write on this subject. My 2002 has been a great snow car for me and it runs great except for that pesky CEL. I am past the point of no return financially with this car and if I could get to the bottom of it and find out what is causing this.. I would be a very happy person. Has Subaru ever ackknowledged that this is a problem? At this poiont I am not asking them to pay..just tell me what it is so I don't have to keep paying. At least on here I know that I am not alone..misery loves company..I guess. Again..many thanks for your reply.
