Hello all,

I have a 2014 6 grand touring and just recently did some mods (nothing too crazy, check out my album if interested), one of which included plastidippin' my wheels matte black. For the project i removed all the tires. after putting them back on the TPMS light came on, i checked the manual and it stated that after a tire change/rotation that it is normal, so i simply followed the instructions on resetting the sensors. but after about 10-20 miles it came back on, this time i checked the tire PSI and found that no pressure was lost in any tire, re-reset the sensor and went about my business. 10-20 miles later AGAIN the light came on. I let the tires sit overnight, check the pressure, and everything is good. Light still comes on and i am having to reset the sensors every time....ANYONE know anything about this???

Did you try resetting it through the dash-screen located where it displays Avg. MPG and Current MPG? I had to find out the hard way and go deep through that menu screen.

Hmmmm...i will go through the settings today and see if i find them there. Don't see why the hard reset would not have worked though??

Yes mines didn't work either, I had to go to two dealerships before one parts dept guy finally told me. You have to go deep into those settings and reset when you want the light to come back on again whether (after 3000 miles or 5000 miles) I believe those are the options. Then you hit reset and the light should go off.

Mine did that after plasti-dipping the wheels also. Just reset the TPMS via the button on the dash. Hasn't been a problem since. Hopefully that's not an issue next time I do that O_O

Our 6 can give us two types of tire inflation warnings. The first is a dummy light on the left of the instrument cluster that looks like the cross section of a tire with an exclamation point in it. This is a warning from the TPMS system to check your tire pressure because one is low or flat. The other is a service reminder that will pop up on the info screen on the right of the cluster. It is a service reminder that can be set through the menu that reminds you to simply check your tire pressure. It can be adjusted in monthly increments and even shut off. When it gives this reminder, you can thumb through the different information screens, and one shows up then that has something like tire pressure with info under it and a back arrow. I am not positive, but I believe when you get to this on the screen you can just push and hold the info button on the steering wheel to clear it, much like you do to clear the average miles and speed. I went into the menu to see how many months it was set for and when I came out of the menu it was reset.

Please read my post entirely for a fix that worked for me.

I have had the same yellow warning light for TPMS come on and after reading all the posts on it there was 1 thing I over looked. I thought my tires were low and they were but just by 5 psi and not enough to trip

the TPMS warning but I still could not get the error to go away. After using the reset button on dash and it still not going away I found that you have to go through the display menus completely and fins the last option in the TPMS menu and turn off the reminder or reset the reminder time frame until it reminds you to check TPMS again. This is not a warning I was getting but just a TPMS reminder to check the pressure in the tires that can be easily confused with a low tire pressure.

I hope this helps others who search for TPMNS error or TPMS warning

Perhaps OT with the path here, but I've seen where some TPS don't stay connected as well at different corners of the vehicle and window tint having metal in it can diminish communications from weaker sensors. Any chance the plastic dip has metal in it?

Do you know if this stuff shows up with DTC / MIL / CEL reading?

Mazda 6 does not use a sensor but Indirect TPMS which measures wheel speed.

Did you manage how to solve this cause I am having same warning after 10-20 miles since i changed front tires. Tire pressure warning on dashboard system settings are off.

The TPMS is my biggest complaint about my 2016 GT so far after 3 weeks. I've had it give me a chime warning 3 times now yet none of the pressures have been low each time I've checked. This "indirect" TPMS is just useless in my opinion and doesnt even tell you which tire is low either. I love this car so much but this is a truly rubbish TPMS....

The TPMS was actually quite good for a long while, until a government-issued update was forced onto any 6 that went through a stealership's doors. The update made the system completely unreliable and more-often-than-not cry wolf.

Wow that's disheartening to hear. I dont know if I'm gonna be able to stand it going off for no reason every few days...

Eventually that will go away.

I swap all 4s for winter every year and it usually complains randomly for about a month (depending on the temperature swings) before it finally gets over itself. I also had slightly different sizes between the sets, so I'm sure that didn't help.

Just keep resetting it and buy a $5 pressure gauge just in case

Yeah I keep a pressure gauge in my backpack so I've checked them each time it's gone off, but it's a major inconvenience to stop and confirm on my 45 mile trip home from work at midnight in the middle of nowhere south GA lol! I'm chalking it up to the major drop in temps we've had the past couple weeks...

Yeah, the "update" made it chime if ALL FOUR wheels change pressure at once, instead of DIFFERENTIAL pressure changes.

Remember, INDIRECT systems work off the tone ring. That is, difference in inflation result in differences in rotation. Ok fine, but if ALL FOUR wheels change at once what are the odds that ALL FOUR wheels have nails in them?

Now go from 90 degrees to 30 degree temperatures and tell me what happens. Uh huh. Or the reverse.

Grrr......

I told the jackwads at the stealer when the car was in for a recall NOT to reflash the TPMS code. They did it anyway. So far I've gotten two BS warnings; both times after a temperature change, and both times getting out the actual pressure gauge showed... no problem.

So indirect is not reliable and tpms sensors cost an arm and a leg and for most of them, you cannot change the battery when it's dwad... That's progress right there

...

And even in my 2018 with tpms sensors I can't get a reading for each tire. A lot of manufacturer have that figured out.

You can get a set of 4 for under $50, how is that an arm and a leg? Also i disagree that there arent sensors as mine first went off while i was sitting still after starting the car and hadnt moved yet.

It depends on the market where you are. The cheaper I can get is 138$ USD including shipping at rock auto for a set of 4. Plus installation. I don't mind paying it up front (and I did get another set for my winter wheels) but I do mind paying it again 5 to 7 years down the road because the battery is not serviceable.

Some model year of the 3rd gen 6 got the sensors and some doesn't.
