Stormy Posted May 13, 2005 Share Posted May 13, 2005 Hi, I've been having some issues with low idle on my 02 legacy gt. I noticed that a plug located under the air box was wrapped with electrical tape. I think it goes to this switch. Is there a chance that this might be causing my problems? Thanks, Stormy Quote Link to comment Share on other sites More sharing options...
Stormy Posted May 13, 2005 Author Share Posted May 13, 2005 The connector is Grey with 2 wires coming from it. One is brown with a yellow stripe and the other is green with a black stripe. Quote Link to comment Share on other sites More sharing options...
Tiny Clark Posted May 13, 2005 Share Posted May 13, 2005 The neutral switch usually allows the car to be started in only Park or Neutral. Quote Link to comment Share on other sites More sharing options...
Stormy Posted May 13, 2005 Author Share Posted May 13, 2005 My 02 is a 5 speed... Do I even have one? Quote Link to comment Share on other sites More sharing options...
felipe01forester Posted May 13, 2005 Share Posted May 13, 2005 That's probably the kill switch from the clutch to the starter. In all modern sticks, there is a safety feature that disables the starter UNLESS the clutch is depressed, so your car won't run away from you if you happen to leave it in gear.

Stormy Posted May 17, 2005 Author Share Posted May 17, 2005 So I did some more "testing" on my idle problem. If I'm driving at about 45mph, put the clutch in and leave it in gear and come to a stop, the RPM's go down to 650~ and stay there. If I put the shifter in neutral when stopped, the RPM's will drop down to 350~. Would faulty neutral position switch have anything at all to do with this???

Stormy Posted May 17, 2005 Author Share Posted May 17, 2005 "PN/PS (Park Neutral Position Switch)- This switch senses if the transmission is in park or neutral. The PCM adjusts the engines idle based on this input. The engine WILL run without this input." I found this here http://www.off-road.com/jeep/tech/4lswap/ Anyone know if this applies to any vehicle with a PN/PS? Quote Link to comment Share on other sites More sharing options...
