2. Indirect TPMS This system does not measure tire pressure directly. Instead, it utilizes the wheel speed sensors already existing in the anti-lock braking system (ABS) to monitor the rotation of each tire. If a tire is under-inflated, it has a different rotation speed compared to properly inflated tires. The system then calculates the pressure drop based on these differences. While this system is less accurate than direct TPMS, it is more cost-effective and is often found in older vehicle models.

Light duty passenger vehicles (LDPVs) are a category of vehicles designed primarily for the transportation of passengers. These vehicles typically include cars, SUVs, and light trucks that have a gross vehicle weight rating (GVWR) of 8,500 pounds or less.
