95 Legacy CEL - how to reset it

uaoSTI · 10-16-2009, 09:18 PM

I am a new owner of a 95 legacy outback wagon (EJ22) that will be my commuter/winter beater. The previous owner said the CEL is from the knock sensor from him using bad gas. I filled it with 91 and fuel treatment but the CEL is still on (only have gone a few miles so no real surprise i guess). I also unplugged the positive in the battery for one minute hoping it would reset the CEL as well.

How can I get the CEL to reset? Scan it (autozone)? Should I unplug the battery for an hour or longer?

no pix because its ugly (seriously).

you can have a shop read it, i'm not sure if they do re-set or not though. solid can for sure. to reset it yourself, pull the negative terminal and pump the brake pedal until the lights don't show up anymore. that should reset it for you. if not let it sit for 15 minutes or so after you do that.

Welcome to OBD-1 Cars.

Go to legacycentral.org and read the thread on pulling engine codes, there are two connectors under the dash that by connecting and turning the ignition on will have the car flash the code for you. This should be the same on your car as it is mine (obd-1 wise) i have a 1st gen wagon, since yours is second gen it might be slightly different.

Now some ej22e bits (I just rebuilt and replaced the ej22e in my winter beater this weekend), the knock sensors are prone to fail, find one with a white connector and make sure the connecting surfaces are clean and free of debris, this sounds simple yet no one checks the surfaces. Odds are the car will throw a 35 code as well (purge vale solenoid), there is a thread on how to wire in a resistor to bypass the solenoid. Uhh there is a thread on legacy central's cite on resetting the ecu as well.

I'd link all the address but alas I'm at work

The only way to fix it, is with a hammer.

Thanks for the help. I just pulled the terminal on the battery and it seems to have worked. Gonna hopefully get it by inspection today.

The 95 Legacy is OBDII.

http://www.sl-i.net is the place to go for 95-04 Legacy info. Legacy Central is more for the 90-94 owners.
