1993 Subaru Legacy Check Engine Light Code 51 Neutral switch (manual) inhibitor switch (automatic)?
I have a 1993 Subaru Legacy AWD automatic with a Check Engine Light that is on. I connected the green connectors and received code 51 - Neutral switch (manual transmission)/inhibitor switch (automatic transmission). How difficult is it to replace this part and how expensive is the part? I've never done one of these before but I'm handy with a wrench and can do many "simple" repairs. If it involves tearing down an engine or pulling a transmission, I cannot do that. Please help me figure out how severe this problem is. THANKS!

I believe you are not getting the right code. Unplug the green connector and find the black single-wire connector under the dash by the steering column and by the ECM and TCM. It is sometimes a bit difficult to find as there is quite a lot of harness there that it sticks out of and only for a few inches. When plugged in it will give the correct code by flashing the "check engine" light. Once the repair is done and you want to clear the code, then plug the green in also and drive the car for a few blocks at forty mph or more and the flashing will go to a sustained and repeated four long flashes. Stop, unplug both the green and the black with the key off, restart, and there should be no more check-engine light.
