WASHINGTON - The National Highway Traffic Safety Administration will by March 2005 determine which of two tire pressure monitoring systems must be in every new light vehicle beginning in November 2006.
Automakers must begin installing monitoring systems in November 2003. They may choose between two types: systems with sensors in each wheel or systems that piggyback onto antilock brakes. Only 10 percent of new vehicles will be required to have any system in 2003, but the percentage will increase for the next two years until NHTSA decides which system works best.
NHTSA estimates that a wheel sensor system can be installed for as little as $13, while the other system could cost $66.
