One of the sensors might be bad or have dead battery/ Many tire shops will test sensors at no charge. Tire does not need to be taken off do test the sensor.

 

Does the light flash a bunch of times before staying lit when you start the car or is it truly always lit.

The button doesn't reset the system. It is used to set the baseline pressure.

 

This a Avalon ?

TPMS battery seems to last 7-10years. Some people will get less, some will get more. If you have a 2013 Avalon + 7/10yrs = 2020/2023; the TPMS batt life expectancy is spot on for replacement.

You need to have four new TPMS installed. Denso is likely the OEM supplier
Non-Denso doesn't seem to work well on Toyotas.

There are YouTube videos of people repla ing the TPMS batt themselves. Ingenious DIYer doing it. A lot of work and time consuming, to save $30-$40 per wheel.

I replaced all 4 of my TPMS with Dorman units back in 2017 after the OEM ones died in my 2010 Corolla. The Dormans are still going fine. I tried Schraeder EZ Sense and they would not program at all. I still have the old original TPMS and plan to replace the batteries in them when the time comes. There are good youtubes on that and they emphasize taking care with the weight of each unit after repairing them. I Have an Autel TPMS checker (TS201) that checks them probing at the air stem- it tells temperature, pressure and battery condition, but will not program. Autel makes another unit that programs and of course it's much more expensive than the (out of production) TS201. Good luck.

 

Tires are correct pressure. Tire light on dash always on. I tried reset. Is there a battery for tire light that needs to be replaced? That’s what our mechanic said. Any ideas? Does sensor need to be replaced?
i will try resetting with button in glove compartment again.
thanks,
Jerry

resetting tire indicator fron glove compartment button doesn’t work

Sorry yes . It is a 2013 Avalon XLS.
thanks

Thanks. I don’t even know where the battery is; I will check out videos. May just take to mechani.

 

DO NOT try and replace these yourself. Good idea to mechanic!

 

Take the sensor out and clean it off. Fixed my 2013 Tacoma. I try the simple and cheapest stuff first. All of the above answers are excellent if that doesn’t work.

 

Thanks Pete. I have to find out where it is first. LOL

 

Battery is in the sensor

 

Is it flashing then staying on? That's what happened to my 2010 Camry. I took it to the dealership and they replaced the bad sensor.

 

yes That’s what happened. Let mechanic do it.
thx

 

Glad my vehicle does not have them.

 

I am in the minority that likes and appreciates TPMS, and I actually check ALL the tires (inclu spare) on a regular basis.

My appreciation for TPMS is due to real life experience experiencing flats while driving at highway speed. Worst situation was when a rear tire went flat while driving on a road trip. The car handling strangely was my ONLY clue to something being wrong. Pulled car over quickly, saw rear tire was flat and destroyed, due to driving on completely flat tire.

Other company cars I had w/ TPMS provided that precious EARLY warning, allowing me to quickly pull over, investigate, swap spare for deflating tire, saving a lot of money: $20-$40 patch job vs NEW single or pair of tires (if the damaged tire was worn a lot).

The drawback of TPMS is the periodic replacement cost (sensor or DIY battery replacement). Small price to pay for considerable benefit.

 

I am in the minority that likes and appreciates TPMS,

Include me in that "minority" too. I also destroyed a tire driving on it flat on a non-TPMS vehicle.

 

I did mine Oct 2021. Had one die from old age and so a new set was required and had ordered new alloy OE fit rims for my winter tires. (No, rusty steel boots ain't something I'd dress my lady in) So I needed another 4. Bought a kit with an Autel TS-508WF with 8 Autel MX-1 sensors, 8 rubber and 8 Metal valve stems. Sent the OE rims to be refinished through my friend's shop. Did the programming and testing before and after myself. Only the mounting and balancing was done by his tire monkey.

Winter tires: Michelin X-ICE3 225/45R18 sale and CT$ promo $683.26 CAD
4 RTX Kazaki OE fit (no need for 2nd set of lug nuts and locks) $785.72 CAD
4 OEM rims restored as new by the best specialty shop in Winnipeg $560 CAD
1 kit Autel TS-508WF w/8 sensors and 2 sets of valve stems $422.93 CAD
** The Autel Kit was cheaper than 8 sensors. And I got a TPMS programming and diagnostic tool to boot.
Total labor cost for all the work involved and dealing with having the wheels picked up and returned $160 CAD

All TPMS sensors work great. Probably because no tire monkey had a chance to program them incorrectly and only one set was given at a time. Eliminating risks from step one.

And 90% of troubles with non OEM sensor issues were caused by the clown that didn't know what he was doing.

WARNING: (I've probably posted this info so many times it's insane. I don't provide links. There a search function on the forum)

A solid lit light with no flashing is a tire pressure related issue or a clown that messed with the SET REFERENCE PRESSURE FUNCTION when one or more tires were not inflated properly. A flashing then solid light means a communication error. IF It triggers after about 20-30 minutes driving normally. 99% of the time it means a dead or dying sensor.

IF a CLOWN tries the SET function to try and FIX the issue with a non responding sensor he will trigger the Famous Toyota ECU LOCK. This is an "as designed never fixed" bug in Yota's LO-LINE TPWS (That's a Toyota with only an idiot light - no tire location and pressure display) It sets the ECU in an endless loop looking for a sensor ID in it's settings that is not responding.

It is such a common human error that Autel has added the ECU unlock procedure to the TS-508 automatically when doing a relearn or a diagnostic procedure on Toyotas. They had to because it was in a separate section and their service help line was flooded by calls "Your sensors don't work... I can read the IDs with the tool but your tool won't PROGRAM them into the car" So they removed it from the tools section and run it by default. Calls dropped substantially.

FINALLY: Programming a sensor is giving a blank sensor a protocol (making it work as a specific car YM)and an ID. Entering sensor IDs into the vehicle's ECU is not PROGRAMMING, IT'S A RELEARN PROCEDURE. WHICH CANNOT BE PERFORMED IF THE ECU IS IN A LOCKED CONDITION!

 

Definitely check your spare pressure.

 

Yes and it is inconvenient. Toyota has the stem facing toward the bottom of the trunk well. I think that is because it forces you to unscrew the hold down fixture. That ensures you get the pressure right and not affected by the clamping of the tire when the hold down fixture is tight.

 

I looked at the TPMS sensors I got off some Lexus Rims from about 10 years ago. They are branded Pacific. And they are not potted with silicone seal, they are potted with hard epoxy. I used a TPMS from NAPA and found a local mechanic that programmed it to work with my ES350. I doubt you can replace the epoxy potting.

If you are able to crack the bead of your tire. Save you time and get a sensor that can be programmed by your local mechanic. Discount Tire was not able to do this for me. I had to find a different independent mechanic that had experience with the TPMS I got from NAPA.

I took my old TPMS sensor from my 2012 Camry apart after the battery died and I had a new sensor installed. After getting the potting that covers the battery off, I found out the battery is soldered into the sensor housing. Definitely not a DIY repair for me and most people.

I had the new TPMS sensor which I purchased from an online Toyota parts dealer installed for a nominal charge by Costco Tire Center.

 

I'm thinking he got it fixed by now...hopefully by a pro.

 

Yoy did not feel flat tire?

Great one right here!

 

Is there any way at all to disable the tire light on the dash without having to remove the whole instrument cluster ?

 

See post #32

 

Maybe someone can explain to me why my 2005 Solara uses a revolution counter --probably the existing ABS sensors at each wheel-- to sense that a tire is low?
(( Note: Tires revolve more frequently at a given speed when pressure is low. )) The rev counter does not use any batteries, and so I'm not out $100-$200 or more to replace any in-wheel pressure sensors.
Methinks Toyota, and the other manufacturers, saw yet another profit center, and abandoned the earlier system.
But, maybe I'm wrong. Shrug.

Simple Rick, it's an indirect and first generation system. Even before TPMS was mandatory in the States. Plus It's an old car. A few years older and it would not have anything. It's not anywhere near as accurate but better than no sensors.

 

What I don't understand is people will change their battery twice or 3 times in the same period for more than a set of sensors that you probably change ONCE in 20 years. And pay more for car batteries than sensors but never complain. It's the least expensive thing to replace over the life of the car. Most people change cars before they need new sensors. It's cheaper than a tire and people don't complain to fork out over a grand for a new set of tires. Half the price of getting spark plugs changed on a V6.

I pay twice as much EVERY year to insure and plate my car.

 

Long time mechanic jumping in here. That first gen system was great. With tires set to the pressure they are going to be run at, also after tire rotation or replacement, you pressed the reset button and went for a ride driving as instructed for relearn. Was no such thing as a TPMS module. The abs system learned the individual tire revs at a certain speed. If at that speed one was different the TPMS light on. Low pressure tire is spinning faster than the rest. Tire sensors last a year or 10 years, pot luck, no matter who made them. And why on earth would anyone go to a chain garage????? And not read Yelp and Google reviews and employee reviews first? The chains are time plus. And God help you you if it's flat rate plus. The plus is commission on anything they can sell you didn't come in for. It's where techs start out, you are the training wheels. If you have AAA they can recommend an approved garage and that is not a gimmick, they have to have a minimum level of tools, diag equipment and ASE master tech. If no AAA find a local shop that has been in business for 30+ years. They must be doing something right. As for dealers, do you really think a tech getting paid .4 hour is going to spend an hour doing the job the right way? I once watched the dealer's lead tech do a timing belt in 45 minutes with a screw driver. Then replacing a transmission, warrantee time, so let's not disconnect the battery. He pops the fuse link. Puts it all back togther, charge light is on. Puts in for a new alternator. This was a brand new Veracruz with 5K on it. HMA comes back and says wait a minute, these alt's never go bad. 5K on it. Dealer had to eat a rental while HMA in Korea had to find one and FED EX it halfway around the world. Hey! this one is no good too!. Service manager finally has me look at it. Fuse. They were going to fire the tech and fast track me through the HMA ratings, but they forgot I turned in my notice. I was fixing what 4 dealers couldn't and getting paid $11 for a 3 hour diag. I learned a whole lot, enough was enough.

 

I had misread and thought that you were talking about sensors AFTER the ABS indirect system when you mentioned pressing the button, Great advantage to being a MOD... Can delete my own posts

 

@jerbo64

Hope you got this figured out!

 

Dissecting a Toyota TPMS sensor:

 

Way too much effort to end up with a iffy sensor.

 

Tires are correct pressure. Tire light on dash always on. I tried reset. Is there a battery for tire light that needs to be replaced? That’s what our mechanic said. Any ideas? Does sensor need to be replaced?
i will try resetting with button in glove compartment again.

Did you check your spare tire? If it's a full spare, your car reads it too. It could be low.
