I get in my car to run some errands today and the TPMS is showing 12psi in the RR tire. I filled the tire with air and found the leak, a roofing nail I took the car to the dealership to pull the nail and lay a patch, shortly after the work begins they call me in the back and show me the valve core is stripped off in the sensor so I had them put the tire back on the car the way it was and went down the road to the place that mounted and balanced the tires in the first place to let them deal with the issue. Apperantly they only have one guy who can patch a tire so they couldnt do crap......I am going back on Saturday to get them to fix it.
Is it possible to remove the jacked up core, or will they have to replace the sensor?
Tire pressure sensors come with valve cores made of a diffrent metal that is not supposed to corode and bind in the stem. They are not to be changed with the everyday valve core. If someone changed them in the past, it's posible that could be a problem.
If the core is bad and it damaged the threads inside the sensor,,,,,,its time for a new sensor. If the core can be removed, its possible to install a new core.
Any competent tire store will have valve core tools designed to remove damaged cores - they work like easy outs. They also have a thread chaser tool to repair any damaged threads on the valve stem inside or outside. If your tire store doesn't have one, I am sure you can do a search on the web to find a supplier. Sure beats buying a new sensor if you don't have to. ??? Didn't know about the special valve core, I wonder where you buy one of those? Good Luck
seems to me the core wont come out, so the tire will deflate... You said your self it allows air in.
Ive had this happen to me in the field a few times(mechanic) just simply take the nut off and push the sensor into the tire, this will deflate it. (this is the proper way to remove tires with TPMS anyhow to avoid damage when the bead is broken.
when your done repairing the puncture install the sensor back onto the wheel and reinstall the tire, these cars tires fit real snug against the wheel so it should air up without a huge blast of pressure.
If it fails to do so, most tire shops have bead blasters which will definately get that sucker inflated.
you shouldnt have to do anything, they shouldnt be removing the core from the sensor anyway the proper way is to drop it into the tire.
