How can I COMPLETELY DISABLE the TPMS on my 2008 Toyota Sienna?
I don't want to put a piece of orange tape over the light. I want the system to be completely disabled. I know how to use a tire pressure gauge. I don't want to replace my sensors. Period. I cannot find anything out there telling me how to do this. Any help would be greatly appreciated!!!!!!
Kind of true. It's illegal for a commercial entity to do so. From the Motor Vehicle Safety Act, (which created the NHTSA) "Making Safety Devices Inoperative":
This language is referenced in the Final Rule of the TPMS at the link you provided (top of page 106). Vehicle owners can do whatever they want, as long as their vehicles adhere to state safety inspection requirements, in which TPMS is not a requirement.
