My wife's car is a 2009 IS350. Got a "low tire pressure" warning in the display. Took it to the dealer and they said 3 of the 4 sensors were bad and that I might as well go ahead and replace the 4th. They want around $1,800. Please tell me these sensors aren't proprietary and that I can go to Discount Tire and have them replaced for much less and they still will work properly. Any good solution besides shelling out so much money for something I can do myself from time to time for free?

 

I'm in the same situation. The check system light came on and the low tire pressure light was blinking for 30 seconds then stayed solid. TMPS is $42.59 each from Denso https://www.densoproducts.com/tpms-sensors-denso

 

The price is absolutely obscene, but the diagnosis is plausible.
TPMS sensors run off disposable batteries that usually last 5-10 years. Yours is on the shorter range of the spectrum, but not out of the ordinary.

They are not proprietary, and you can go to Discount Tire and have them replaced for much less and they still will work properly.
Chill.
It's gonna be alright:

You can order a set of 315Mhz sensors from a competent tire store, or Tirerack.com, and have the new set of sensors swapped for the old.
These worked for me:

You might have to initiate TPMS re-learn cycle on your car by pressing the TPMS button under the dash (google for your model's specific location).

They aren't proprietary, however I bought a new set of rims and had the tires and TPMS sensors installed on my 24 IS350 at Discount tire and they wouldn't work properly. Discount tire had to order the Toyota Brand sensors, tear down the rim/tire, and reinstall them. It was around $350 for the Toyota sensors installed, and they work fine.

Pretty sure they are not 433mhz, but regardless you can go to any major tire shop and have them replaced. They will need to be programmed to the ECU so you cannot just install them and press the button. The shop should be able to program them into the ECU also.

 

Same for my IS250-C and the advice from my Lexus UK dealership is as follows. They have never had much success with aftermarket sensors and urge to use the Toyota/Lexus ones. Cost including programming would be UK £1,000 (US $ 1,300).

I have solved the problem by sticking one inch of black insulating tape on the binnacle in front of the amber LED. Doesn't have to be Toyota tape - any make will do.

 

Thank you for the links and your post. I do have the box of the one TPMS Sensor that Costco installed. It is 315MHz and the mfg. is Dill. I'll go back to Costco and ask them to reset it. I've bought 2 sets of Michelin tires from them over the years and I find that Costco stands behind their products. Will post an update when the saga ends. Thanks again.

 

My wife hersreplaced last week at Discount Tire for $120

 

My 2007 IS350 Sensors were going out. Went to Costco to get new sensors. Costco could never get it them to work. They said to go to Lexus to see if they can get them to work. Lexus could not get them to read. So Lexus put Lexus OEM ones which worked. Returned the Costco sensors to Costco.

 

I had Discount Tire change all mine recently with 3 of their own sensors, and one Denso sensor (550-0103) that I already had. No issues so far. Previously, I had all my OEMs until 2018 when I replaced one of my TPMS sensors with a Denso 550-0103, ended up replacing that one too just because the battery was already getting low on it.
