TPMS warning light flashes then stays on
Hi everyone! Just had my first ever problem with my Yaris. But it's a minor one. I had new tires put on in May. No new rims or anything like that, just new tires. No issues. Then, today, six months later, my TPMS warning light came on. I expected this, since we just had the first hard frost of the year, and my tires always lose some PSI after the first hard frost. No heat in my detached garage, so it gets cold in there. Anyway, I put air in the tires, like I always do when this happens. No big deal, right? Except this time, the TPMS warning light wouldn't shut off, even after I drove 50 miles on the highway. Now, when I turn the car on, the TPMS warning light flashes several times then stays on, which the owner's manual indicates that there's a malfunction in the system. I did a search of this forum and read that sometimes this "malfunction" is simply that the batteries died in the TPMS sensors. Do you think this is the case? I've owned this car since new, and the TPMS sensors have the original batteries.
Or is this something I should just ignore? This car is over ten years old, so is this TPMS problem just a typical "old car" issue? I don't want to spend big $$$$ on fixing a nanny system. But on the other hand, if it's likely something simple and inexpensive to fix, I'll consider getting it fixed. Thanks everyone! |

06YarisRS - Dash warning lights driver me crazy, too. I couldn't stop staring at the TPMS light, even though I knew the tires were totally fine. I don't check my tire pressure often, but looks like I may have to check it frequently during the winter months, if there's no reasonably priced solution. By "reasonably priced," I'd be willing to pay maybe up to $200 to fix this. If it's going to cost hundreds more than that, it may make more sense to use tape to cover up that warning light. I'll also take your advice and try disconnecting the battery at some point to see if it'll reset.

If they are ten years i would start with the TPMS sensors, probably a dead battery.
Visit a tyre shop who has a TPMS scanner tool, if they cant read all 4 wheel sensors then you also know which one is dead. Or disable the system. http://www.yarisworld.com/forums/sho...highlight=tpms

Anytime the light is flashing there's a problem other than low tire pressure.

I just did the tires on my truck. A 2008 ram. I've had dead sensors for 2 years. You did well if they are only dying now.

Okay, quick update to this thread. We've got a blizzard on the way, so I decided to pump a little more air into the tires just in case they lose a PSI with the sudden cold coming. I slightly overinflated all the tires, to 35 PSI. And the warning light went completely away. Wow! And this wasn't a one-time fluke. I turned my car on and off four times throughout the day while I was running errands, and the blinky malfunction dash warning light never came on. I'm glad I was able to fix the problem for free, and it wasn't a dead sensor battery!
So, if anyone else gets a blinking TPMS malfunction warning light even after you inflate the tires to the proper PSI, try overinflating your tires to 35 PSI, and no less than that. This is what worked for me, for some reason. Do this before you run to the dealership. I have no clue why overinflating the tires worked, but I'm not complaining!

Glad to hear the annoying light is gone.

Perhaps whatever gauge you use to check your tires is out of calibration. Maybe the tire really was underinflated.

The gauge I used to check the tires was definitely correct. I checked with a different gauge, and got the same readings. But even if the tires were underinflated, that wouldn't explain the flashing TPMS error light. Must be some glitch with the car's computer, I have no other explanation. Hopefully this thread will help others who find themselves with the same issue! |
