Neutral Safety Switch

[Code2]

Like others I’m in the replacing mine tho I’m not as lucky as the rest of you who have changed.


The top bolt came out nice and easy the bottom nut came out nice and easy

Went to remove the sensor and it wouldn’t come off. Took a wire brush to get some of the gunk of it where those little compression wings are and on fell off then another. Last 1/4 wasn’t moving. Sprayed it with some pen oil and let it sit

Went back with a little pry took and well the sensor came off but the metal ring that you put the lock nut and washer on stay on the vehicle so I have the sensor off just need to figure out how to remove the metal attachment that fit on the box shaped piece stick out of the tranny


Any ideas? I’m thinking I may just use the dermal to cut it the metal to remove it

Are you talking about this? Pretty sure that is part of the trans and is not supposed to come off.

That square piece I known isn’t suppose to come off it’s that metal ring that’s on the switch that compresses onto the square part that’s stuck on there so we’ll that it completely popped out of the sensor when prying

 

[Code2]

See the metal ring that’s seize on the square piece it broke out of the sensor housing. So it’s becoming a challenge getting it off since there isn’t much room to work and get a good angle

Ah, that sucks, must be same reason KenWilliams's 6 hour job. I would probably go with a flex shaft on a die grinder with a carbide burr. Seems like a cutting wheel might be problematic in that small area. Might be worthwhile to remove the exhaust, but that may also have rust problems and likely need new gaskets.

I’m thinking most of the people with this issue are in the rust belt?

NE, so yes. Mine broke too, I had to mangle it, but I was still able to pry on the ring and eventually free it. Dremel is the next best bet.

What a pain in the ass

My question is with the new sensor does a replacement rubber oring come with it the one behind this nut didn’t fair well lol

Best, fast way is just cut the damn thing with Dremel or Oscillating Tool, just do not cut into center shaft, then insert flat slot screw driver to open it and remove it. clean rust on shaft, apply some grease and slide new in.

Hope the new one goes on without a fight......

Now I know why I didn’t because a mechanic and instead became a paramedic.

Actually the 4Runner was garage kept. The actual sensor was clean and the contacts inside where nice and shinny.

My 2014 4runner just started acting up and I am thinking this is my fix.

First I noticed reversing out of driveway and then going into drive it felt weird. Get a minute up the road and then notice 4lo flashing. I wasn't even out of my neighborhood yet so I pulled over and checked to make sure I was actually in H2, shut the truck off and turned it back on and it was fine.

Then when I got out of Home Depot and started truck back up it was doing it again, 4lo flashing. The gear selector screen is blank (not showing P, N, D etc like normal).

I ended up turning it off again, starting up and going into 4hi, 4 lo, and cycling a few times and then was able to drive home without 4lo flashing again.

May just order the part to get ready to replace it. I am guessing mine is going to be corroded and not a fun time.

For those with a 2011 thru 2016 here is the newest part number for the safety switch ordered it Monday was at the house by Thursday night

There was another part number in the thread with like 60050 or something that’s the old version confirmed when I called and verified by vin

While putting it on was not as simple as just sliding it on, it went on with some grunts and maybe some grease and maybe small lean hammer of course tapping it on with the nut to protect it and maybe a file �� but it’s on and problems so far are gone

If this helps in the sensor breaks away from the compression collar what I did was take a dremal ever so gently and tried putting a seam on the top hoping a screw driving would finish the rest by splitting it open. After several f bombs i sprayed the hell out of it left it for the night. My hands took a beating they are to big to fit in the area.


The next night I took the good old trusting last ditch tool a small locking vicegrip locked it on the nut straight with the nut and the used a screw driver between the nut and teeth and pried back on the vice away from trans it moved a bit so I adjusted the wrench again repeating it over and over till it popped off.

error code: P0705 Neutral safety switch replacement

My 2013 4Runner SR5 with 100k started displaying an error code P0705 with the 4lo blinking and trac off light on. It would intermittently come on when the car got wet and then go away when it dried. I called Toyota customer service (800-331-4331) to get the part# 84540-35061 (neutral safety switch) because I thought I could save some money doing it myself. For kicks I called my local Toyota dealer here in Minneapolis and they quoted me $195 for the part and $98 for labor. That was far less than others on this forum were being quoted so I had them do it. Maby it helped that when I called my local dealer I was able to tell them what I needed. Hope this helps.

I got to this point and the visegrips wouldn't work for me. My secret weapon was a slide hammer. 4 or 5 taps and it slid right down the shaft. The dremel did no good at all. Couldn't get the right angle for a good cut. Clean the exposed shaft with some emery cloth and spray liberally with pb blaster. Applied some anti seize to shaft and dielectric grease around the collar when installing the new one.

Another data point on this issue.

My 2016 TEP had thrown code P0705 a few times starting this year, and since late last year the shifting mechanism as sticky at times. Vehicle is at around 45,000 miles, in the southern Canada rust belt.

I had the problem serviced at my local Canadian Toyota dealership. All amounts in C$ and following standard Toyota Canada shop charges...

Diagnose P0705 (0.5hr): $70
Techstream Data Charge: $17
Part 84540-35061: $284
Part labour (2.0hr): $280
Total including VAT: C$736 (about US$610)


The $87 for diagnosis is a bit funny since code P0705 is pretty obvious what the problem is. But I know it was going to be covered, so..

Toyota performed the diagnosis but would not perform the repair until I removed my aftermarket skid plates.

The part number is the updated version of the part introduced in 2017. Hopefully it is not as vulnerable to the corrosion problem.

Service writer says the tech took more than 2.0 hrs since the factory part was basically fuzed in place.

Service was NOT covered by the Powertrain warranty.

Service WAS covered by the Toyota Financial Services Vehicle Service Agreement (TFS VSA) "Platinum 7/100" extended plan I purchased online with the new vehicle in 2016.

EDIT: TFS VSA Platinum only covered 0.9 hours of shop time total (diagnose+install) and not the full 0.5+2.0 hours billed to me by the dealer.

2016 4Runner NSS

Couldn't get the right angle for a good cut. Clean the exposed shaft with some emery cloth and spray liberally with pb blaster.

I too have this same stiff shifter and randomly it'll work fine, other days (especially after a rain) it malfunctions. I gearing up to try to purchase a replacement and have a go at it as well. been soaking it with penetrating oil on and Off in preparation, hoping I can get the part , i havent yet tried to find one, will begin this weekend, fingers crossed.

SO is there a retaining clip on that SHAFT protruding thru the NSS? or just that single bolt up above, and it will allegedly slide off towards me (if I'm lucky lol)?

Update:
I was able to obtain a new NSS, I see now what folks are talking about where the unit might be corrosion or rust fused to the transmission rod. I see now this bolt with locking ring when tightened squeeze's the protruding shaft.

I'll try to post my experience removing the old one and fitting the replacement.

Would coating this in dielectric grease from new and undercoating the vehicle every year ensure this won't happen?
