Tire Pressure Sensors

[cmailliard]

I ended up damaging a rim on my 09 F150 and have had the spare (with the good tire) on for a couple months. If I buy a new rim how does the Tire Pressure system work? Is it built into the rim or what is it? Would I take the sensor out of the damaged rim and put it in the new rim? Just kind of stupid on this and want to make sure before I drop a couple bills on new rim.

Thanks

Back when I worked on cars I remember them being attached to the valve stem on the inside part of the wheel so I would think it would just move to the new wheel.

as long as the sensor wasn't damaged you should be able to install it on the new wheel

Yes you can reuse the tpms. The ones on my truck are 12 years old. Careful the tire places have a huge markup on tpms, so buy one on amazon if you need to replace. If you het a new one it will need to be programed to your car. On some toyotas that is a pain.

Added: If it has a replaceable battery, this is the time to do it. Most late model cars use a special valve stem the the tpms sensor attaches to, sometimes you can replace the stem separately, sometimes it is integral to the tpms.

Thanks all. I think I do need to replace the batteries cause I was getting sensor faults before the incident.

Tpms sensors are re usable, they have a tiny hex screw on the bottom of it that goes into the stem- the stem itself may not be re usable if you take it out of the rim, if your carefull and use soap on it it should be ok. And on these there are no serviceable batteries. They have about a 7 year lifespan depending on conditions.
