How do i read my CEL , 93 imp! - Subaru Enthusiasts Car Club of the Sierras

Howdy!

does anyone know off hand how to check an ODB 1 , engine code? My 93 ever since i bought it would throw a check engine code if you tried to go up spooner in 5th gear. it would lose speed in 5th so i just always drive up in 4th.

Now it started to get the check engine code in 4th gear. A buddy suspected it could be knock ...

but the dummy method of putting in some 89 didn't make the problem go away (although i got slightly better gas millage somehow)

Thanks

If it's like the SVX, it involves inserting some jumper pins into a diagnostic plug and counting the CEL flashes.

Ya, , i had figured out that i have to "connect wires" but i don't want to randomly connect wires down there and hope i don't destroy my ecu. Searched on nasioc and google have not found a single diagram or explanation of What to connect. some mention a green wire... in what looks like the OB1 clip i have 3 green wires... green with white, green with red stripe, and larger green & red

there's also a single green wire with a female end, (and one more with a male end) ?

anyone have Experience doing this?

You're probably going to need a service manual. You might want to check the SVX manual here: http://www.seccs.org/tech The connectors might be the same since the two cars are of similar vintage... but the SVX has a lot of one-off crap on it too, so YMMV.

Shit, I had a bunch of good links on my old hard drive to lists of codes and pics of the plugs.
I know its green plugs, well one of them is

. I think they are taped or bundled together under the right side of your steering column. If I can muster up some ambition to put on shoes I can go out and confirm colors for you.

awesome, thanks

and some of my wires aren't in the exact stock location due to taking out my dash and part of the wiring harness for cage install. i know of a singular solid black, and a singular solid green both with male/female, then there's a odb1 block with maybe 6 or 8 wires...

I may have to run over to storage and dig up the service manual.

thanks for the links i'll give it a shot

Thats the two plugs, 1 yellow wire to one plug, 1 black(or dark) wire in the other plug.

That sounds nothing like the SVX, which has a white connector and two blue jumper pins, IIRC.
