Tire sensors

[Pjrebordao]

Do the tire sensors rely on batteries?
One of the rear sensors stopped giving readings and the yellow tire light turns on every time.

Thanks

Yes they do. Shelf life seems to be varied but anything at about 5 or 6 years onwards and they are at risk of losing battery power.

Ok. I guess replacing the battery implies removing tire from wheel ?

Yes that is correct.

Batteries are not replaceable. The entire sensor must be replaced

The units have a few parts:

- Battery
- Accelerometer
- Transmitter
- Pressure sensor

Your car is listed as a 2016. Ten years is a good service life. I'd replace all four at once.

The 1180-B units are listed as supporting your car. While a training tool is supplied, these units are auto-sensing. Once the wheel is spinning, the accelerometer switches the unit on. The battery powers the pressure sensor and transmitter, then announces the pressure to the car. When first installing my wheels, the sensors reported to the car with the first few hundred feet/tens of meters.

The radio signals are picked-up by a receiver towards the rear of the car, in the area of the parcel shelf. This is the same receiver which picks up the key fob frequencies. Ultimately, the Body Control Module gets the information and puts it on display.

Discount Tire and other sites will sell their house brand. Most of these pieces will work just as well as Ford's. They often have enough inventory turns where you get fresh units. Being electronic items, I prefer the Ford units. YMMV.

Avoid eBay and deep discount sites; these often sell dated gear with dead batteries and counterfeits. I'd avoid buying from rim & tire "stylin' " shops; you don't know what it is they're installing, how old it is.

I had Costco replace all 4 in my '12 Edge a year or so ago. Right around $200/$240 otd.

I suppose that until they get replaced there's nothing to do about the warning light...

Desculpe, não notei a sua localização.

Não há mais nada a fazer em relação à luz. Ela permanecerá acesa até que o problema seja resolvido. Depois de fazer a substituição, você terá tranquilidade por muitos anos.

Sorry, I didn't notice your location.

There is no other action to take for the light. It will remain on until the problem is cleared. Once you get those replaced, you'll be good for many more years.

Anybody remember the old days when we didn't have those?
We used to drive around until something felt weird and we pulled over and delt with it...lol
OP, my 2 fronts went out recently but were replaced when I got new tires, no rush. Just waiting for the 2 rears to go.

As others said, buy OEM and replace all four. If one gave up, the others will start failing anytime soon.

I’d just disable the TPMS all together, that’s my two cents.
