all sensors are bad and i cant afford to replace/repair them. I want the check system light to go away so i can see my range and how much miles i have left for the tank. Is there anyway to check how much miles i have left with the check system on?

 

You can still check with the check system warning on but whatever category you are on (tank mileage, temp, etc...) will only be visible for a few seconds until the warning indicator returns.

I am looking for a fix to the warning light myself until I get new sensors.

 

Old thread, and OP hasn't been here since March, but... https://www.clublexus.com/forums/is-...7-is250-3.html

tl;dr: 13 years and nobody found a way to disable it. Some 2IS models came without TPMS standard, but requires different ECUs (specifically, Korean body ECU which you'll have to live with a few issues if you go that route. Absolutely not worth it due to cost/hassle). Set of new sensors tends to run around 90-120. Refurb 4 pack will run 60ish.

 

The refurbished 4 pack price sounds about good. I'll have to get a set swapped in when I change my tires here soon.
