Siemens VDO Automotive Corp. launched a line of aftermarket tire pressure monitoring system (TPMS) components at the recent SEMA Show in Las Vegas.
Siemens' new TPMS parts include hardware that should be used anytime a tire is dismounted or replaced, as well as a ``self-learning sensor'' that eliminates the many different recalibration routines required on specific makes and models of cars, said Howard A. Laster, Siemens' director of marketing and business development.
The TPMS components include the sensor assembly and five service parts: a valve core, valve nut, valve cap, seal and seal washer.
The sensor need only be replaced if it fails or is damaged, the company said. However, manufacturers recommend that all new service parts be replaced each time the tire is serviced.
Unlike other vehicle parts that may take six to eight years before needing replacement, the new Siemens units represent a ``new sales opportunity'' for tire dealers, Siemens said, in that tires on vehicles equipped with TPMS units can require repair or replacement from the day it is driven off the lot.
