NoahDL88 Posted March 28, 2006 Share Posted March 28, 2006 There are probably over 100 individual codes that could be wrong, however, i do believe there is a way for you to check for codes yourself, however i don't recall how. Seeing as the cats were replaced recently, i'd make sure that your o2 sensor is plugged in, as that could very easily been left unplugged.

ctoth Posted March 28, 2006 Share Posted March 28, 2006 Go to autozone and they'll read the codes for you, usually for free. That will give you an idea as to what is going wrong. Quote Link to comment Share on other sites More sharing options...
idosubaru Posted March 28, 2006 Share Posted March 28, 2006 Go to autozone and they'll read the codes for you, usually for free. That will give you an idea as to what is going wrong. that is only for OBD generation vehicles. not sure what years this is applicable to, but his 1990 legacy won't have OBD plugs so they can't help him out. normally this is an excellent method for diagnosing the Check Engine light. i'm not familar with 90's legacies but if it has the LED read out of the codes, follow those directions posted and you'll be golden. easy to do and you can do it yourself if you can count blinking lights.

idosubaru Posted March 28, 2006 Share Posted March 28, 2006 what engine do you have an EJ? there is information on how to read those codes yourself posted above i believe. if not, you can find it on the board somewhere. often you don't need a scan tool to read the codes.

idosubaru Posted March 28, 2006 Share Posted March 28, 2006 what engine do you have an EJ? okay it is a 2.2 liter, i looked it up. i'd read the steps in the links posted above, they should help you figure out the codes yourself. most likely you don't need a scan tool. i just read through those links, that is what you're looking for. no scan tool needed.

jamal Posted March 29, 2006 Share Posted March 29, 2006 A 90 Legacy is an ODB vehicle and you don't need a scan tool. There is one available though. All you need to do is connect the black plugs, turn the ignition to on, and the CEL will flash the codes. There are two sets of plugs and a port for a Subaru Select monitor. The black plugs are for simply pulling codes. The green plugs are for active diagnostics. You could also make one of these: http://bbs.legacycentral.org/viewtopic.php?t=16219 Also, how hard is it to use some punctuation and check your spelling? This isn't pre-teen chat.
