I was hoping for some help here. I just purchased a 91 Subaru Loyale and the engine check light is on, so I took the bottom part of the dash apart and I found the 02 monitor and made sure all the test connectors were unplugged. I turned the key to the "on" position and I counted the red blinks and it just does 5 short blinks and keeps repeating. Does anyone know what that code is? I disconnected the battery for 30 seconds to reset the codes, and it went away till I turned it off and turned the car back on.

5 short blinks are the vehicle model designation i.e. MT, 49 states and Canada.

thanks, I just figured that out an hour ago. Engine check light is still on though.

Connect the test connectors and then count the flashes. On my 92 loyale, they are under the hood, up by the brake master cylinder. There is a pair of green ones, and a pair of white ones. The green ones are the test connectors.

 

Read this, and save it to your favorites, you'll need it again .

Does "Engine Check" light mean that it's time for the car to have it's XXX-miles tune-up, or does that not apply on a car that old?

Doesn't apply. There are no service reminders on older Subaru's.

 

For stored codes, you need to connect the white connectors for the "read memory" feature.

Ya, I figured it out, I connected the white and green ones to reset the codes and then it started to tell me the actual code. It was 34 which is the EGR, so we got one from another Subaru, cleared the codes, then started it back up and it works perfectly, even passed the IM test with flying colors. Had to replace almost the whole exhaust system too, had holes all over it. It runs great now.

i have a 91 loyale and cannot locate any of these connectors, like some previous owner really changed some things. Any suggestions how to find them?

They could be tucked up high or possibly taped to the wiring loom. 

You have to get right in there, it’s not obvious until you know where to look for them.
