What to do about a broken tpms sensor

MushroomStick

So I had a flat tire today and it went flat in such a way that it somehow crushed the tpms sensor. When I get a new tire, will I be stuck with a warning light on the dash if I go with regular valve stems instead of replacing the sensor? I have a 2010 Mazda3 sport hatchback and have been unable to find the correct google search to answer this.

Yes, you'll likely get the lights if you don't buy a new sensor.

You may be able to permanently disable the warning with an OBDII unit. Or, if you're looking to die, you could pull the fuse (I'm assuming the fuse doubles something important).

You will absolutely be stuck with the light if you get a regular tire valve.

Even if I go regular valve stems for all 4 tires? What do people usually do when they have say another set of wheels with winter tires on them?

You won't be able to get safety inspection in most states with the tire pressure light on.
Did you check the price yet? I know one for my wife's car was stupid expensive but it was a VW so that was expected.

Yeah, its expensive - especially for a feature that I do not like. I'm in Illinois, they only do emissions testing.

How could you not like TPMS?

But yes, you will need to disable the system somehow (I'm sure there are guides online) if you don't put in a TPMS in the new tire.

The sensors have been the only point of failure on my car. They make getting new tires cost nearly a grand. So far, having a tpms on my car has been more hassle than it's worth. There's been nothing for me to like.

Any competent tire shop should be able to put on new tires without replacing the TPMS. The only thing that has to be replaced are the valves, and those are only a few dollars each.

1) Buy a new sensor
2) Buy a flash tool and disable all the sensors. I know they exist for Jeeps, but I'm sure they exist for your car

They buy an additional set of sensors and deal with the shitty resyncing. Which is why I didn't do this.

Also note that it's possible any kind of traction control you have will shut itself off if one of those tire sensors is going off. Mine does which is why I didn't go the "no sensor" route.

i don't know where you guys are getting your sensors but when i got my new tires it cost like 8 bucks a tire for new sensors i think

Sensors are a bit more expensive that that (a quick look for the OPs car shows them as low as $36/tire), but under normal conditions it should only be a few dollars for a rebuild kit (essentially just the valve stem assembly and maybe a new battery).
