Is everyone's TPMS just a useless pain in the ass?

I believe it blinks for a few seconds then stays on all the time. I left my TPMS sensors on my winter setup cause its more of a pain to check pressure in the winter and didnt opt to buy them for my summer setup. I'll just deal with the light always on I guess.

As long as there's no constant chimes or bells.

TPM Light

We have had the same problem for a long time, now at 33K miles. Similar excuses from the dealer. However, I read the instruction manual and it says that a computer, PDA or cell phone can interfere with the signal transmission and cause the problem. Well, we always have one of those in the car!

Next service interval I will require that they fix it or disable it. I suspected the spare and checked it. Not a bad idea - it only had 24 psi pressure. These little spares need much more air than that. But, pumping up the spare did not extinguish the light.

I'm also going to write to Mazda customer service. If enough of us do that they might come up with a solution.

I have an update to this. I was having a problem the same as the OP, intermitent TPMS reports, pressures always fine. A few weeks ago, I changed to a different set of wheels that have their own TPMS sensors, and the problem is competely gone. Same pressures, same cell phone/electronics, etc, similar temperatures, same commute route with the same elevation changes. It has to be one (or more) flakey sensor. The problem is that since it is intermittent, and there are four of them, diagnosing which is faulty is very difficult. I bought another set (used) and will swap all four into my other set of rims next tire change.

I posted this elsewhere, but I'll repeat it here: I filled my tires to the recommended pressures on the coldest morning we've had so far. Four or five days later, when global warming resumed, I got a TPMS alert. The front tires were at 38 psi and the rears were at 36 or so. I let enough out to take them back to 34/32 and it quit complaining. I like the feature, but my 300C only alerts at too little pressure, not too much.

I got my car in the fall. My dealer told me the light would come on when it got cold. A week later it got cold and it came on.

I did what he said to do...
Let about half the air out of the tires, then fill them back up again to the right preasure.

I did that and the light wen off and stayed off, I have had 10 degree days and 70 deg days.

FOr you guys having the problem, have you let a bunch of air out and put new back in? I know you are going to say "air is air, it shouldn't matter" and you are probably right, but this worked for me.


I blame the Japanese air they fill the tires up with when the car is manufactured. The air JDM air doesn't seem to be compatible with our American roads !!! Try some American air!!! just kidding.

make sure you realize temperature can have something to do with it... id imagine with our lower profile tires even stock it wouldnt have a real impact but it might condense the air a little inside... caused mine to come on a few times, just cold weather did it. who knows.
