My 2002 SC430 has factory tire pressure sensors. I believe that all models after that have them too. The give away will be the dash warning lights. When you turn the key one notch, all of the warning lights should come one. Look for a warning light for low pressure. The tire sensors are battery powered. They need to be replaced approximately every 10 years. Once replaced, I recommend having the Lexus dealer program the computer to properly read the sensors.
