ok now i have had my rims on my gs for about a week now and never had this stupid light come on and tonight im driving and it comes on and i got home and checked my manual and it was the air pressure light !!! i have search the threads of this forum and hadn't really found a answer on how to disconnect or turn of that annoying light. Another thing im wondering is if anyone had the master warning light come on at the same time as the tire pressure light ??? Any ideas or fixes would be appreciated.. THANK YOU

 

my understanding from my previous post is you rest the master...did you not have the tire pressure sensor installed on your new wheels?

 

need to reset the tire pressure sensor. and did they put on the sensor on the new tires. the stem of the sensor is a faded aluminum color

 

no i did not have the stem put on.. do i need to do this?? or is there someway to bypass this??

 

needs to be on there.

or u can try this i havent tested this yet

get the sensors put them in ur car and reset the tire warning light. that might bypass it but im not 100%

the reason i say that because durring pdi's i dont put the correct air pressure in the spare(if it has 1) i just do all 4 and reset the light

 

but wouldnt the sensor be near each of the wheel? if he put all 4 in the car it might not be close enough to read it if the sensor was close to each of the 4 corners?

 

Where the heck is the reset switch? According tot he manual, its under the steering wheel, but I don't see it.

 

it's there you have to get on your back w/ a flashlight it's there...

 

How does the tire pressure stem communicate with the car?

 

there's some sort of receiver, either on each corner of the car or in where the spare tire is that receives this information.

 

They work off of a radio frequency (RF). On some cars, they are location-specific; the sensors need to stay on the same corner they came from because some cars have the capability to tell you WHICH tire is low on pressure. This means that they will need to be re-coded when rotating the tires- typically easy enough if you know the procedure and have a strong magnet. Not sure if this is the case with the Lexus, though.

Just putting one in the corner of the car probably won't do it because they'll read only one atmosphere and will "tell" the computer that all four tires are flat.

Your tire shop did not mention this? Oops!

 

VVT-I Do you know what color wire is to bypass the TPS on the GS ? https://www.clublexus.com/forums/sho...e+sensor+light

 

So there is no way to disable this feature without cutting the wire?

Is the dealer able to disable this?
I'd hate to have to go get the stupid sensors out of my old wheels...

 

PM koolaid something or rather...he's a lexus tech and should know.

 

My light came on for a while and I couldnt figure out why since all the tires were at the right pressure. I called my dealership and the SA told me to air up the spare and the light went away ever since.
