TPMS question - can the TPMS check system light be disabled

Hi fellas
My check tire pressure system light came on recenly while driving. Pressure is fine, the light is not the light you get when a tire goes low. Basically you have the blinking icon, etc.
I took it to my wonderful service advisor, robert at lexus of riverside (btw he is a great guy and I recommend him for those in the inland empire / riverside area).
Anyhow, one of the sensors has died, unknown cause at this point as the sensors were not removed for diagnostics.
We have several options and wanted to get input from you folks. One option, replace the bad sensor .....option 2, get all new sensors (either oem or aftermarket) and have dealer initialize them.
Option 3....unplug the brain ..... safety concerns aside, has anyone done this on the 3gs ?

I was planning to try this on my GS. Anyone done it already ??

If you check your tire pressure with a good gauge, like the old days, then you're good. You'll know if you get a flat/blowout.
I'm all for disabling the system, but if you want the functionality from here on out... it will cost you, what I'd say to be 4 sensors.

just was wondering if anyone has done it on the GS300/gs350 ? Remember, we are not ones to take no for an answer....

I suspect as batteries die on our sensors, this will be a greater issue....I am OK with not having that functionality....it is not a huge deal for me. I check my pressure and actually look at my tires myself.

Hey at the Dealership we Run into people who don't want to pay for the tire pressure service to just buy a small doughnut or a wheel off a dolly to stuff all the sensors inside of the tire and that tricks the ecu. there is not much ways around the tire pressure system because it is legally binded by law.
but a blinking sensor light usually is a tire pressure error and most errors are low batteries. so your best bet is going to Toyota getting them to price and set them to the ECU and you put them in a spare that your not driving on.

thanks for the input..... From what I have researched, aftermarket sensors can be purcahsed for as little as about 125-150 a set. Then all you have to do it have the dealer program them to your car. Of course if you have them, there is no reason not to spend another $20 a tire and swap them in your wheels. That is about $300-400 job total. i am thinking I dont want to spend that on the car.....I just dont care for the system....time to take apart the dash console....I remember seeing the ECU for this....let me dig up the pic

Try to disconnect the plug and see if the system shuts down, the ecu is located above the navigation. But I have a suspicion it will be more difficult to fool the system.
You dont really need the tpms it was basically designed for soccer mom's in ford explorer's that were running the old firestone tires

ok just unplugged the tire pressure ECU, it sits above the radio unit, accessed by removing the radio / nav unit. It has a single plug. The light stops flashing and just comes on solid LOL. So it is not a fix on the 06 and later GS vehicles. Time to get a new set of pressure sensors.

UPDATE : I bought a set of EZ sensors
http://www.ez-sensor.com/
got them at rock auto
Went to america's tire and for $20 a tire, they swapped the sensors in and programmed them to the car......total cost 145 for sensors plus 100 for swap over with tip

or you could have put black electrical tape over the tpms light on the dash and saved yourself $245
but the replacement tpms you got is the proper way to correct the check system light.

No you cant do that....you see just like when the tires are low, 3 different lights come on, a yellow tire indicator, a red triangle i think and a CHECK SYSTEM in the center display and you cant see your mpg or whatever your display normally states. any of these errors literally diables your dash displays with MULTIPLE lights

hello. am i to understand that there is no way i can 'bypass' the ECU for TPM sensors on my 2006 GS300? I really do no need or want this feature and it is costly to replace batteries. Would love to be able to 'disable' it. Thanks for your help.
