Recently purchased a 2005 SC430. Previous owner replaced wheels/tires & I do not know if the sensors were transferred from the factory wheels or replaced. The 'low tire pressure' warning light is on & stays on. All tires are @ proper pressure. I've looked for a reset button & have not found one. Any thoughts on how to reinitialize the TPMS to talk to the new wheels/tires ???

Thanks, BIGSTIX

 

this link will help you get started on the TPMS journey.
You can also disconnect a cable in the console to disable the TPMS system and the light will go off…I believe the procedure is in the stickies.

Your TPMS sensors may need to be replaced. Remember, your SC needs special color sensors, not the generic black ones.
