Park sense issues.......

[ungucpho79]

Make sure the valve stem is at the 12 o clock position.

I had sensor issues for a long time, figured out the valve stem has to be at the 12 o clock position and every incorrect warning stopped

It's impossible for the valve stem to be at the 12 o clock position on the stock tire carrier. It can be at 11 or 1, but not 12, due to how it is located on the rim.

I've just moved mine to the 1 o clock position, so we'll see if that helps.

At the dealership with our JLU now - came in for the defrost recall flash and asked - while it's here, please check park sense, make sure it's all working fine, and explained the situation...........
Some days it worked perfectly, other days it had a fit. Today on the way in there were not "park sense unavailable, clean sensors" message at all - it just worked on the 40 minute drive here.
The other day, it worked part of the driving we did, and didn't for other parts.
Will have more info when done but the sales guy I normally work with here said that they did some research and apparently there's some STAR documents about sensor orientation? We'll see.......... I told them if it's the tire cover then we own the problem, but I'd like to know for sure.

Just drove back from the dealership - no issues driving in this AM so driving back with no issues really isn't proof of anything because the problem came and went - was only present about 1/3 of the time (a wild guess)
However, they did do a lot of digging, checked every individual sensor, checked all wiring, looked for any codes present and so on and tried without the spare tire at all, and actually did end up duplicating it with the spare tire on at one point (they spent a fair amount of time with it - a couple of hours).
The work order/invoice indicates they went to "Tech2Tech" and did some searching and as said here earlier that if the spare tire was positioned with the TPMS sensor other than 11 or 1 o'clock, it could cause "ghost issues with park sense".
WEIRD because those sleep when not spinning/in motion! There's nothing happening with that sensor, it's not broadcasting anything - in order to conserve battery life. They sleep when not on a wheel in motion. But there must be something about the electronics or the antenna that causes what the work order literally called "detect ghost objects behind the vehicle".
Time will tell, but it must be a real thing - they quoted "went into service library, searched Tech2Tech common issues" and found the issue with TPMS/valve stem positioning.

Semi-unrelated, but do you know if the TPMS sensors wake up under any non-motion conditions? Or how fast they fall asleep?

Wow, I always wondered why the valve stem would impact. Never thought it would be the TPMS doing it.

Wish I knew!

Thanks -
Big shout out to Stew Hansen's on the west side of Des Moines, Hickman Road.
They actually literally spent a couple of hours working on testing, checking, rechecking and researching. Most would have shrugged and said "it's ok now, there's nothing wrong with it"
It was fine coming home - that's not proof necessarily as I drove it over there with no park sense issues, but - they tried really hard and found others with similar issues. That counts for something, in my thinking.

Anyway, a thought - if anyone else is having this issue with stock JLU Rubicon 33" tires - check and see if this helps. It's at least worth the time it takes to remount the spare.

I think the sensors are just kinda finicky. I have a similar problem - been running the same 33" KO2 take-offs for over a year. Did a 5-tire rotation about a month ago, and ever since, I get a warning when in reverse. Dash indicator shows it's on the left side (both the far left and the next indicator over are flashing).

I didn't make any changes to the bumper whatsoever - just rotated the tires. Have cleaned the sensors, camera lens, etc. No dice. If I remove the tire, it goes away (but obviously that's not a solution).

I'm about due for another rotation in a couple of weeks - interested to see if it goes away then.

Mine did this from the factory. 2024 Rubicon X. I took it in with 100 miles on it to get it checked as it was brand new. They literally rotated the spare on the holder one rotation to the right. The TPMS sensor was interfering with the park sense stuff. I can reproduce by putting it back.

Give that a try!

Make sure the valve stem is at the 12 o clock position.

I had sensor issues for a long time, figured out the valve stem has to be at the 12 o clock position and every incorrect warning stopped

That made mine mad. Needs to be to the right on mine!

 

[rcadden]

Yeah, I'm still dumbfounded that this worked, and irritated, as well. I know for a fact that until about 10K miles ago, I *always* had the spare tire valve stem at the 6 o clock position, because my OCD would have demanded it be so.

However, I rotated it so that the valve stem is above the centerline, and lo and behold, all is well. I just have to pretend to not remember that it's off kilter back there.

I have a 2023 392 XR that does a similar thing. Stock tires and wheels. Everything still stock.
I did rotate spare tire to where valve stem is at 1:00 position.... has made no difference.

Most Fridays I drive Jeep to shooting range which is around 15 miles away from home. I get a Park Sensor Disable Clean Sensor every time. I get no warning when Jeep is cold, backing out of garage. I get no warning when backing up leaving the range, after an hour or so. But just before back home, I stop and drop off a passenger that lives a couple of doors away from me, and when I put into reverse to back out of his driveway is when I always get the Park Sensor Disable Clean Sensor warning.
Say I drive to grocery store around 10 miles away, shop 20-30 minutes and come out, back out of parking space... no warning.
So it seems that if I let Jeep sit for a short amount of time between stop and go...I get no warning.
But, if I drive Jeep for a 10-15 mile trip and have to back up without a cooldown period...I get the Park Sensor Disable Clean Sensor warning.
Jeep is always clean, garage kept. And this Jeep is mainly on-road driving for now.

Spare holder needs to be modified so the Jeep is upright, dead-on 6:00,
valve stem should be dead-on at 12:00
and the star pattern of the lugs is a perfect upright star, not up-side-down star with point at the bottom.
The whole spare tire carrier is designed wrong - by someone standing on their head.

It may be because having two of the three lug nuts holding the top that wants to fall away from the carrier is better than just one up there. At least that is what I tell myself.
