Neutral Position Switch Removal?
Hey, maybe I'm just missing something obvious because I've searched and can't find any info on it, but I'm 98% sure my Neutral Switch is broken (the one on the transmission). I want to pull it off to test with a multimeter, but I can't seem to figure out a good way to get the thing off. Does anyone know how to do it with the car on jackstands, or is it something I need to get it on a lift to do? Thanks!

I have a retarded question... What does that switch do? I'm pretty dam sure mine isn't plugged in right. From what I know it just detects if the transmission is in gear or not correct?
If the reverse switch and the neutral switch got cross connected what would happen?

Its a switch to tell the ECU that your transmission is at "neutral", so the idle won't just die off.
you can't cross connect any of them, it goes in only 1 way. (different kind of connector)

I could have sworn they were the same on mine, but maybe I'm lucky and just happen to match them up every time
but just so we're clear, I'm referring to both the white connectors for the neutral switch, not crossing them with the black connectors of the reverse switch.

Hm, so after messing with mine trying to unsuccessfully get it off, I needed to drive somewhere so I just dropped the car and decided to try again another day. BUT strangely everything seems to be working now...I'm guessing either a harness connector was loose or I have a short somewhere. I guess I'll just leave it alone for now and see if it starts acting up again.

Major thread bump, I know.. But I'm having the same issue.
I already have a new sensor in hand and I got under the car managed to get one of my wrench to fit on but I just don't have room to loosen it. Any special tools or tips guys???

The cruise control also won't engage if the PCM thinks the car is in neutral. It took me a lot of head scratching for me to finally figure out that the trans shop incorrectly installed a sealing washer on the reverse switch during a rebuild, which was holding it out of the engagement area. The PCM could see that the switch was reading neutral despite also detecting and indicating speed through the ABS sensors. It would throw the switch code and the cruise control wouldn't work, but the switch itself tested fine. We could see the detent moving in out moving the shifter without the switch installed and decided to try it without the washer and voila, everything waJs back to normal. Looked at another trans later and theres not supposed to be a washer in there.

There are past threads on this. Some buy a deep socket and cut a slot on one side with a grinder for the wires to slide through while you tighten it down. Some use a crows foot on a socket ratchet. Taking the PPF loose and letting the trans drop down is probably the easiest thing to do.

^ may be easier but not exactly cheaper to do on your own.
