Tire pressure sensor light now stays on with change to new tires: how do you reset this?

[Guy in WNY]

I presume you've checked your tire pressures and they are all OK? But even if they are out of whack, wouldn't resetting the TPMS button make the light go out anyway? So, it does sound like a bad sensor someplace.
Why it decided to show up after the dealer did work to your car is what I can't understand.

when you tried to reset the switch did you hold it for like 5 seconds until the light in the dash flashed.

If they rotated the tyres, then inflated the fronts (brought forward from the rear) and deflated the rears (brought back from the front) to match stock pressures, it could just about be enough to trigger the warnings.

Check the pressures with a decent gauge - filling station air lines have notoriously inaccurate gauges - and if they're where you want them, press the reset button.

Notwithstanding the increasing prevelance of TPMS, it's good to tell one's tire shop to watch out for and not damage the TPMS.

Your dealer's quote of $200 sounds about right. One sensor alone is a little over $100, plus there are installation/sensor registration charges.

you may be referring to me. the tire shop owned right up to it and bought a new one and is taking care of the issues with registering a new TPMS with the car ($96 quote from toyota). I cant see myself ever paying to get new sensors if the ones i have now fail. i could see getting all new sensors installed costing more then a set of really nice tires. I will have the black tape ready.

So it was all because they were under-inflated? How long ago was this and is the light still off? On my last oil change I requested they put in 38 psi. When I checked later, all 4 tires were nearly the same except one was slightly under -- I filled it later, and the light still remains on. What's strange is that the sensor issue happened soon after this maintenance, which was over a month after my actual tires were replaced. But the dealer assured me the sensors can't get damaged with just oil change/tire rotation.

Yes I did that as stated in the manual. I imagine there's a trick to get it to shut off permanantly. I'm certainly not dumping $200 into this.

I actually stopped going to the dealer for oil change and tire rotation with the purchase of 4 new Michelins. Up until last month, I went to a Toyota dealer every single time in order to keep up with the policy of my Extra Mile Tire Warranty (which turned out to be worthless by the way).

The saga continues:

Just got back from original tire replacement shop (well known chain) and they used an electronic tool to check each sensor. All 4 checked out as "active", which I take it means OK. I watched them perform the procedure.

Toyota claims THEIR (more expensive) tool says that one is defective, and they want to charge over $200 to "fix" it. Tells me to ask how much tire shop will reimburse for damages. Tire shop management doesn't return message.

No one mentions anything about re-programming internal computer............

What a pain in the *ss. I'm about to crack this case with a piece of black tape. Been driving for 20 years without these d*mn sensors. But then what happens when I go to sell/trade in?
