Tire Pressure Monitoring Systems (TPMS)

  • Overview
  • Benefits of TPMS Registration

  • Registration Process

NSF International offers registration for identifying tire pressure monitoring system (TPMS) sensors that have been tested on vehicles, function in their intended manner and meet federal regulations.

TPMS registration provides third-party assurance to consumers, shops and insurance companies that an aftermarket TPMS sensor meets all applicable federal requirements and will fit and function properly in a manner equivalent to the original equipment (OE) sensor on the vehicle(s) intended for use.

To earn NSF registration, TPMS sensors must meet the following requirements:

  • Compliance with FMVSS 138 (Federal Motor Vehicle Safety Standards). Testing is performed on at least one vehicle per protocol for each sensor
  • Functionality and performance testing which includes accurate location reporting, sensor accuracy, low pressure warning repeatability and sensor ID write test for sensors with cloning capabilities
  • Compliance with 47 CFR Part 15, Radio Frequency Devices

Benefits of TPMS Registration

NSF TPMS registration allows manufacturers to demonstrate to consumers and regulators that they can trust that tire pressure monitoring sensors fit and function properly.  Tire pressure sensors that meet all federal regulations and functional requirements will be listed on NSF’s website.

NSF registration sensors will also appear in Tiremetrix’s TPMS Manager®, providing shops with the background they need to service vehicles equipped with direct TPMS. Tiremetrix is a leader in TPMS software development. Having Tiremetrix’s TPMS Manager® software highlight NSF registration sensors will help shops identify high quality sensors.

According to a 2003 National Highway Traffic Safety Administration (NHTSA) report, an estimated 78,392 crashes (including 414 fatalities and 10,275 non-fatal injuries) occurred annually between the years of 1995 and 1998 due to flat tires or blowouts before tire pressure monitoring systems were installed in vehicles. NHTSA estimates that TPMS reduces by half (56 percent) the likelihood that a vehicle will have one or more severely underinflated tires.

Why Work With NSF

Our history of testing and certifying products for over 70 years ensures that certified automotive parts meet rigid quality, safety and performance standards. Manufacturers of high quality parts can distinguish their parts and brand, compared to others in the marketplace, by using NSF certification to show equivalency to OEM service parts in form, fit and function.

In addition, we have global reach and automotive expertise:

  • We have a global presence with strategically placed offices in key automotive markets in Asia, Europe, Australia and North America.
  • Insurance companies worldwide recognize and support NSF certified parts for collision parts replacement.
  • NSF knows the automotive industry. NSF International Strategic Registrations (NSF-ISR) is recognized globally as one of the premier registrars of automotive manufacturing facilities. NSF-ISR’s extensive automotive client list includes both OEMs and major parts manufacturers.
  • NSF offers services throughout the auto supply chain, including parts certification, distributor certification and collision repair shop certification.

Registration Process

The registration process includes meeting federal regulations (i.e. Transportation Recall Enhancement Accountability and Documentation Act), vehicle test fit (VTF) and functionality requirements.

  • The TREAD Act mandates the use of tire pressure monitoring systems technology in all light motor vehicles to alert drivers about underinflated tires.
  • Vehicle test fits verify that the sensor functions like the original equipment (OE) service sensor when installed.
  • Functionality requirements include service functionality (e.g. tire rotation and ensuring that the pressure values and location report properly).
