2017 Fiat Pop hatchback flat tire sensor

[Remzi500pop]

Im sorry if this has been answered, i could not find it. i have a 2017 Fiat pop hatchback. the flat tire sensor came on about a month ago. but there is no way to reset it. the control pannel on my model does not have a reset.. and after having the tires air reset and after driving around its not resetting. still shows one tire with an issue. it was cold one morning and one tire was 1lb lower than the other 3, so it went off.. after you drive for 20 min they all warmed up , no leak, just one tire seems is 1lb diff than the other 3. since my model has no reset . . and it had been like that for over a year, it jsut came on when it got cold and all the tires dropped down to 26lbs. do i need to make them all the same and then try driving for it to reset. seems to only go off when the pressure drops below a certian lbs..? whats confusing is when i google how to rest it, all other modles have a way using the dash console to reset it. .but mine does not have the tire option. ? help. any one know how to fix this? thanks in advance.

It sounds like you have a bad sensor, that's all. They can replaced at most any reputable tire shop.

I thought so but it adjusts, its reading or the pressure is going up and down with the other tires.. seems to be reading correctly.. just keeping the light on for some reason.

On the 500 if you filled the tire to the correct pressure. There isn’t a reset button. You just drive the car a couple miles.
It will rest it’s self.

If it's like my experience with TPMS on the Abarth check your front tire pressure. FW little hatch needs higher pressures up front cause all the weight is there. My door stickers indicate like 38 or something. Back when I first my fiat, my TPMS was doing the same thing, on when cold off when hot because I had all 4 tires set to a generic 32psi. System does not like that and will do what you describe. Found this on another site, but if you have larger tires they require higher pressure as per the chart, but again go with what you have on your door stickers, assuming you have stock tire/rims that went with that car. If you're tires are really set to 26psi I'd say that your TPMS is right, you have low pressure.

I know it's a Pop, but just an FYI.

Sport - 195/45 16 F 35 R 30

I actually keep mine at F 37/38 R 32

If it should be the in-tire sending unit...I have been informed that the battery in OEM sending units are not replaceable.
