Hi,

I bought a 2008 RX 400h from an individual. It was in excellent condition upon purchase. Within 30 minutes of owning the car I took it right to Firestone for 2 new rear tires.

As soon as I got in the car the Warning light and Tire Pressure Light were lighting up my dash.

Firestone took it back, tried to reset it but no luck. When I took it back and left it, they determined it must have been the tire pressure sensor that all of a sudden went bad at the very moment my tires were changed.

A new tire spensor was put in.

Guess what? Those pesky lights are still on. Firestone is suggesting it's something electrical and to see the dealership.

I read some on-line help that suggested confirming aluminum valve stem caps. They all match.

Then I am reading about the spare tire pressure sensor...how can that be? The spare tire wasn't touched. This seems to be a common suggestion but I just understand how a spare tire not on the car could make this light pop on.

Has anyone had this happen? And please tell me there is a simple fix. :)

Much thanks!

So, did that work? I'm having the same prob with my 2002 SC430. I just got the upgraded disc 3 months ago. Grrrr
