Chris4141 Posted July 15, 2011 Share Posted July 15, 2011 For the first time since I purchased this vehicle new, the check engine light on my 2002 Legacy L Wagon M/T w/112k mi, came on a few days ago and has stayed on. I did try several times to take off/on the gas cap, but to no avail. The vehicle seems to be running just fine, but don't want to ignore it for too long. Does this warrant a trip to the dealer and how much should it cost to check the codes? I heard Autozone can pull the codes for free. Should I go there first? Thanks in advance for the advice.

Suzam Posted July 16, 2011 Share Posted July 16, 2011 (edited) Free is good. Stop by Autozone and have the codes read. Then you'll have the answer you need as to what the next step will be. Why pay someone $$$ to plug an ODB II reader in? BTW at 112k you should have already done the timing belt and other 105k service.

Fairtax4me Posted July 16, 2011 Share Posted July 16, 2011 What he said. Have AZ scan the codes for you, but post up the actual code here before you let them talk you into replacing parts. Quote Link to comment Share on other sites More sharing options...
Rpm90001 Posted July 16, 2011 Share Posted July 16, 2011 If you happen to get a p0325 pick up a knock sensor while your there. I just had to replace mine 122k. Quote Link to comment Share on other sites More sharing options...
goof_ball Posted July 16, 2011 Share Posted July 16, 2011 The autozone I went to a few times just gave me the scan tool and let me do it myself in the parking lot. Write down the code(s) then clear them all to see if they come back. I had a cel come on after replacing some items. I cleared the code and the light never came back on. Just a weird glitch I guess.

Chris4141 Posted July 16, 2011 Author Share Posted July 16, 2011 Thanks for the responses, I'll plan on running over to Autozone so they can plug in their OBD-II. BUT...the check engine light is off this morning. Can they only obtain a code if the check engine light is NOT on? Can they obtain a code from some kind of memory which caused the light to come on yesterday? Quote Link to comment Share on other sites More sharing options...
ocei77 Posted July 16, 2011 Share Posted July 16, 2011 Can they obtain a code from some kind of memory which caused the light to come on yesterday? Yes, it's in memory, unless you unplugged the battery etc. O. Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted July 17, 2011 Share Posted July 17, 2011 I know some older cars had codes that would disappear when the light went off. Your 02 should store and save any code that gets set, so long as the ECU does not lose power. Quote Link to comment Share on other sites More sharing options...
phxmotorelectri Posted July 17, 2011 Share Posted July 17, 2011 Everyone should have their own code reader... my gosh, they are only $45-$60 dollars. Reading a code shouldn't be sich a big deal. A code reader should be given away w/ each new car purchase... never mind, that's never going to happen w/ a code reader maintaining a car has never been easier, but then shops would loose out on a full half of their repairs. AAA figures that a full 50% of ALL repairs are unneeded. I believe that % is correct... maybe even a bit low. Quote Link to comment Share on other sites More sharing options...
Rpm90001 Posted July 17, 2011 Share Posted July 17, 2011 I know mine will lose the code when the problem is corrected.. Example. P0325 knock sensor in my 2000 legacy replaced and drove it to the cottage 50+ miles away, checked it with the scanner when I got there and if was gone. My scanner is older actron, it did not bring up the old code, as long as it is corrected I believe they disappear. Quote Link to comment Share on other sites More sharing options...
