Hey new member here. Don't blow me up for not searching the forum, I just wasn't able to find the answer I needed upon searching.

2005 Legacy GT

So here's my problem, I'm getting a recurrent p1518 trouble code- starter switch circuit low input. I keep clearing it and it keeps coming back. I am having no trouble actually starting the engine until after I clear the codes. After clearing the codes I have to turn the key to the off position for 10 seconds (this is what my access port tells me to do) then it takes about 5 seconds of holding the key in the ignition position before the engine starts. This only happens on the first start after clearing the code though, after that it has no problem starting. However, sometimes it seems dependent upon how far I push in the clutch pedal, if I push it too far it just doesn't start so I back the pedal out an inch or so and the engine starts up no problem.

On other threads people are saying that it is the wiring between the ECU and the starter switch and this seems to be the case with my car as well. Does anybody know how I go about repairing this connection so that I can get rid of this CEL for good? Or does this sound like an entirely different problem?

I have a new battery also.

Thanks in advance!
