Thread: TPMS question

This should be a simple question, at least I hope it is.

I had a tire that I was occasionally having to add air to get worse, to the point of losing 22 psi overnight. This morning I go to take the tire off and see if I have something in it that I can plug for the time being. Getting the tire off was a complete issue in itself. F^CK whoever put this back on last, and F^CK GM for their cheap ass capped lugnuts.

So anyway 45 minutes of fighting later I finally got the wheel off. I go to put air back in so I can start searching for a hole, only to find that that valve stem is broken. Its the actual threaded part that that cap would screw to that is broken, the stem itself is in one peice and would probably hold air, but I need to get this fixed. I was looking on RockAuto and a few other places and this is where I need your help. Its hard to tell by the descriptions, but do the TPMS rebuild kits come with that part, or am I going to have to bite the bullet and get a whole new TPMS unit?

Thanks in advance.

i work as a tire tech at a local tire shop.. a sensor rebuild will not replace that part. it only replaces the nut on top, the valve core, and washers and crap. your gunna need a whole new unit or just put a rubber valve stem for now if you dont mind the tpms light..

Grf, exactly what I expected. From what I have seen though the Dorman replacement has that as a servicable part. Do you see any issue why I wouldn't be able to use the Dorman replacement, or am I going to have to stay OEM? I was considering replacing both rears when I get tires in a week or so, and if I can get by spending $70 instead of a lot more, that would be better.

as long as its the same part number i dont see a problem with it.

most tire shops should have a tpms scan tool to reprogram everything

So I am taking it, no matter which replacement I get, its going to have to be programmed? I need at least one, and if my guy doesn't have the proper tool to program it, at least it will be in place until I can find someone to do the reprogramming.

My wife's 08 town country van had 3 break in 3 years. When it was out of warranty and putting new tires on I had them all replace with normal rubber stems. The aluminum ones keep corroding. Chrysler now equips there 2012 vehicles with rubber ones with the same specs(433mhz I think) but I can not find out if they are compatible. Anyone have any idea?

its most likely gunna need to be programmed to the car. watcha could dew it remove all the sensors the take out the light bulb for the tpms lol

Haha. The help is appreciated. Going to call my friend to see if he can still get me the same deal on tires, and see if he can reprogram the TPMS. If he can't I'll still order the sensor, have it put in when the tire is broken down, and have another shop program it.
