LS430 2004 Sport Suspension, I have checked tire psi 34 , Spare tire as well .
Turned ignition to on and held reset switch under the dash for 3 sec and plus.
Nothing happened , light is still on , No system initializing came up. Manual say there could be a malfunction , Whats is this going to cost ??
I have a Req Maint on the dash , Does this need to be cleared maybe for the low tire light to go off as well ?? I hope.

How much $$$
Is there a way to pull these sensors or bypass this wonderful warning light ? I don't want to be in to a $1000 for a spare tire sensor.

but did you initialize it?? ^ ^ ^

The spare tire has no pressure detection. The 04 Lexus does not use pressure detectors in the wheel. It utilizes the computer (with its ABS circuit) to detect a difference in wheel speed.

All of the 04-06s are this way, right? This makes buying and swapping as set of winter wheels / tires a much simpler proposition.

I understand that on my Lincoln MKZ, there was a mid-year improvement in 2007 to add wheel sensor TPMS. I am lucky enough to have an 07 without that feature, so I can swap my winter and summer wheels / tires with impunity.

As Sojah said - Did you INITIALIZE the TPMS ????

No Initialize . Nothing on my dash . All i know is the Low tire message went away after 12 attempts . I hope it does not return.
