I have a 93 Legacy Wagon and I am trying to run the ECU codes. I am having trouble finding the second black connector. Do I have to remove the ECU?

you may need to remove the tcu to find the other connectors

Thank Josh. I am not off of work till Tuesday and will check it out .

Ok I found the connectors. They are on the right side of the steering colomn in my car. After running I came up with 11, 21, 32, 34, and 11. My brother (a chevy mech suggested that I do the battery trick to clear the codes, and go for a drive, then check again.) I come up with just 21. The temp sensor. I went through napa and they gave me a brass colored single pole sensor. Is this the correct one or is it the one next to it with the big connector?

 

Thanks

The single wire sensor is for the gauge.

 

The two wire sensor is for the ECU, and that's the one you want.

Thanks Josh, I guess I'm back to the store.

 

You guys have been awsome. I have learned more from you guys then I have the local suby dealership. They could not tell me wich one it was.

 

Thanks again

Jim

glad to help......either the dealership is stupid....or just didn't want to help you....

I finally got and replaced the temp sensor and just wanted to let you know alls well and a big thank you to everyone.

Reset the ECU (disconnect battery for 15 minute) anytime you change a sensor. The ECU has to "learn" the replacement sensor.

I did not know that. Will go out and do it. Thanks, you guys are awsome

ok, cleared the codes and then rechecked. still come up with a 21

777... what colors are the two wires? I couldn't tell on one in the pic.

 

Thanks

You may try leaving it disconnected longer than 15 min. I did that and it did not clear my codes, however after about hour and a half it did while I was working on the stereo. You could leave it off overnight and that is a gaurentee.

I have heard one thing on that however, let your car idle for about 10-15 min to let it relearn without pushing on gas or driving it. I have heard of others having problems and have experienced them myself with connecting and getting in for a test drive.

connect both black & green connectors to clear the codes. Instructions for this method are on my site.

 

 

I'm not sure the color of the wire that the connectors are connected to. One is yellow.......how come you want to know?

Because I am trying to figure out why the sube engine in the back of my bug won't start, and, well, the connector got hacked off looong ago. Just trying to make sure I have the right wires.

 

I'm gonna start a new thread, so feel free not to reply.

gotcha.....i'll have to look in my fsm's. What year did you snag the motor and wiring from? do you have the combination meter in there to blink, or have you rigged something up?
