A TPMS is an electronic system designed to monitor the air pressure inside the pneumatic tires on various types of vehicles. TPMS can be divided into two different types - direct and indirect. Direct TPMS employ pressure sensors on each wheel, either internal or external. The sensors physically measure the tire pressure in each tire and report it to the vehicle's instrument cluster or a corresponding monitor. Indirect TPMS does not use physical pressure sensors but measure air pressures by monitoring individual wheel rotational speeds and other signals available outside of the tire itself.

If the model year (MY) is supplied when the VIN is decoded, such as from a crash report or a vehicle registration record, the MY value will be the supplied MY, even if the MY decoded from the VIN differs from the supplied MY. If the MY is not supplied when the VIN is decoded, the MY value will be decoded from the 10th character in the VIN.
