Tire pressure warning?

I had a flat several weeks ago and had to replace the tire. We moved the spare to the left front and replaced the right front, which then became the spare. Since then, the low tire pressue warning for the spare has been on. Jeep had it for two hours, said it was fixed and would re-set with 10 miles of driving, but they were mistaken. My husband has lowered and raised it and checked the pressure, with no results. This tire didn't give a warning when it was on the right front. Thoughts?

Re: Tire pressure warning?

you should have a round magnet(looks like a hockey puck) that recalibrates your pressure. i would check manual(my liberty has one, i just got my commander so i haven't had to do it yet) sorry if this doesn't help:)

Sounds like your dealership didn't do what they were supposed to do. I've gone in w/ low pressure warning on the spare during an oil change, and they took care of it sight-unseen, the warning gone immediately when I picked it up. I recently had them rotate in the spare, and when I drove it away it had no issues. There should be no "break-in" period, they should've re-calibrated it at the shop. (Perhaps they didn't actually air up the flat tire?)

Where was the donut located in your liberty? I'm to lazy to go outside and look in my owners' manual. Thanks...

Re: Tire pressure warning?

The Commander tire pressure monitoring system doesn't use the donut-shaped magnet like the older Grand Cherokees or Libertys to recalibrate sensors. If you rotate the tires yourself they will reset after 10 miles over some minimum speed. I'm not sure if the dealer can reset without driving it, but it does sound like there is something wrong with the system.

Does anyone have the oem part number for an 2006 commander. I was looking up the sensor by application on 1stjeepparts.com and for the nut and sensor for an 2006 it says it will run around 22.00 a piece. When searching part numbers on here though it seems that the part number comes up 34.20 a piece. Trying to make sure I get the right sensor to put in my rubicon wheels.

If you are installing them in new rims you need the nuts too of course ... the part number are listed with and without nuts usually

For the 2006 Commander the Item # shoud be 68001696AB (With Nut)

That' s a good price you have they list for over $50 here

I have a different part # for the '06 XK TPMS.

I have a different part # for the '06 XK TPMS.
That's the part number for the sensor only without the nut ...

... there's three different part number for this part, one is the seonsor only, one is the nut only, and the last one (I posted) is sensor and nut together.

That's according to my reserch anyway .. I have never actualy ordered them ... but I checked the info at three web sites

I've noticed that the 2006 OEM Tire Pressure Sensors do not work reliably when the ambient temperature goes to freezing or less (when you really need reliable TPS function). My dealer has done a sensor/sender replacement, but the TPS device still is not working when it's cold (freezing or below). The dealer has not addressed a possible problem with the receiver (very expensive).

Anyone else see this problem?

I've experienced a bit of trouble with the TPMS. Twice on long trips in the cold and wet at highway speeds. The yellow caution will come on. When I checked the dash reading, I get two dashes instead of numbers. Usually it has trouble reading the left rear, but it may move around or even clear up entirely. Then come back on later. And just to irritate me further it sometimes indicates the spare tire is low. Did I mention the cold and the wet? This gremlin obviously gets perverse amusement out of stopping me to have me crawl under the Jeep in the snow to check the pressure on on a pristine spare tire.

I can't replicate the problem on my own, let alone for the dealer.

I have a question on the tire sensors. Are they mated to the vehicle? The reason I ask this is I needed to a new tire mounted for my spare. I left the tire at the shop, and the light stayed on. I checked the pressure in the remaining tires they all were fine. Just curious

They are specific to model year, meaning some will only work on certain model years.

sorry about my question: but i wanna reset the spare tire pressure..how i can activate the sensor if the wheel is not spinning..??
thanks
 
#20 ·
The wheel does not have to be spinning for the tire pressure to update.
 
#21 ·
so how i have to do make my jeep understand that now the spare tire if ok??
is not true i have to go to the dealer with the sensor number to add it??
thanks a lot

Okay, recently I went on a trip and the tire pressure light on the dash started flashing then goes out. Stopped and checked all the pressures including the spare and they were all good. It's been a few weeks now and randomly the light comes on and flashes for about 30 secs and goes back off. I wasn't sure if it would flag a fault code, so I hooked up the scanner, and nothing. Has anyone else have this problem? I figured I would let it go for awhile, since I travel a lot for work. But now it's starting to bother me. Ay suggestions would be great.

Same problem

Did anyone answer the question? I had a flat, swapped the flat for the spare. Sensor correctly showed the spare as having low pressure. Got the flat fixed, put back in place and put the spare back in place. Sensor continues to say that the spare is flat. It seems that it needs a reset somehow. By the way, the spare is now inflated to 42psi so i don't have to keep topping it up, so that is not the problem.

Did you ever get your issue fixed?? What was the solution?
 
#24 ·
thats the way i solve it: i went to dealer and he reset me all the sensor ( i guess plugging the car to diagnose) and after a few km was working fine.
but you put back the same tyre or you swap it?

About 2 years ago I had all tires loosing pressure from bad valves on the TPMS valves. Under warentee they replaced all 4 sensors and valves. They forgot to do the spare so I was always having to refill the spare when the EVAC said the spare was low. Had a new spare put on, and rotated the tires including the spare several times now.
Bottom line I NEVER had to do anything for the sensors to work - they took care of themselves. Never even had to wait or drive.
