TPMS Warning Light Problem - Mazda3 GT

[HatchbackNDN]

Highly unlikely to be a fuse. Most likely a bad sensor or on the very very rare event, a faulty antenna (body side). Lemon Law isn't that easy, not in most states at least. Mostly in the Republican states is the L.Law so straight forward. I'm just saying. Also, if it's still pretty cold in your area you may be experiencing "low temp. induced PSI"
*if you have 34 psi @ 75F and then the temp drops to 65F the next day, your psi will also have lowered 1 psi...33psi. So 10 degrees F +/- will increase or decrease your psi 1 pound.

I was going to make a new thread tonight about this, every so often my car will beep very loud four times and I am thinking its because my winter wheels dont have TPMS sensors. Has anyone else experienced this?

^no, if there are no sensors at all, the light will flash but there won't be an audible alarm.

If the sensors are installed and reading an out-of-spec value, that's what makes it beep at you.

If you have no sensors and still get a beep, that's another issue... or you do indeed have sensors in the winter wheels without knowing it! What color are the valve stems on those wheels?

Thats what I thought, I am not sure if they have sensors or not cuz they came off my dads old MS6, my valve stems appear to be black rubber...

not that it matters that much anyways because I will probably be putting my summer shoes back on in the next few weeks (sssh)

K so i have a 2007 mazda 3 sedan that i haven't had very long. I had a tire pressure light that stays on but all my tires are fine and at the right psi. I decide to finally take it to the deal to see if i can resolve this problem. I just had an alarm and a remote start just put into it and the mechanics at the dealer said that the alarm and remote start was interfering with the pressure signal and he can't get a reading out of any of the TPMS. Then he tries to scare me with that my computers could be fried from the remote start, so what the heck do i do now and the mechanic doesn't want to go any further with the car until the alarm is removed. So I decide just to go ahead and check the forums. I go with the advice under this thread on fuses, so I check the fuses and notice a sunroof spot but I don't have a sunroof and there wasn't a 7.5A in its place. So I decide what the hell I'll just go get some fuses to see if that would work. What do you know, problem Solved! I couldn't believe it. The dealer couldn't even resolve something as simple as that! wow

Your new "add-ons" are using the same communication frequency that you TPMS uses. I had the same TPMS problem. When my 07 Mazda 3 GT was built at the factory, they inadvertently had the TPMS and the rain sensing wipers using the same frequency channel. My dealer changed the circuit board behind the rear view mirror and put the wipers on a different frequency. The problem was corrected instantly. Check to see if your newly installed alarm and remote start are available on a different frequency.
