Direct TPMS, or direct tire pressure monitoring systems (direct sensor TPMS) refers to the use of a pressure sensor directly mounted on the wheels or tires of a vehicle. [1] The pressure inside the tire is measured using a pressure transducer with the pressure information being subsequently sent to the vehicle to warn the driver of under or ...

2022年3月1日 · Vehicles on the road today could have two possible types of tire pressure monitoring systems (TPMS). Either indirect meaning the vehicle has no pressure sensors in the tires or direct where the vehicle has individual sensors in each tire. Let’s take a deep dive into each of these systems and learn how they work and how to diagnose them ...

2021年4月1日 · Direct TPMS uses pressure monitoring sensors within each tire that monitor specific pressure levels – not just wheel revolution data from the anti-lock brake system. Sensors in a direct TPMS may even provide tire temperature readings.

Direct TPMS (dTPMS) directly measures tire pressure using hardware sensors. In each wheel, most often on the inside of the valve, there is a battery-driven pressure sensor which transfers pressure information to a central control unit which reports it to the vehicle's onboard computer.

2018年7月6日 · What you need to know about Direct TPMS and Indirect, ABS Based TPMS systems. Another common question we get is regarding direct and indirect Tire Pressure Monitoring Systems . Indirect TPMS works with your car's …

2024年11月8日 · Direct TPMS Sensors. Direct TPMS sensors measure tire pressure in real-time from inside each tire. These sensors provide accurate pressure readings and communicate directly with the vehicle’s onboard computer. Most direct TPMS sensors integrate with the valve stem and typically last between 5 to 10 years.

2022年11月15日 · Direct TPMS uses battery-powered sensors in each wheel to directly measure air pressure in each tire and wirelessly transmit that information to the TPMS computer. Indirect TPMS uses the same wheel speed sensors used by the anti-lock braking system to measure differences in the speed that each tire spins to estimate when tire pressure has ...

2025年1月31日 · The Direct TPMS monitors the air pressure using sensors in each tire while the indirect depends on the data from ABS. The system processes these data and then alerts the driver if there are any abnormalities.

Direct TPMS. In a direct TPMS, the tire pressure monitoring system sensors are in the tires. Their location enables them to take direct readings of the air pressure in the tires. However, direct TPMS sensors cost more than indirect sensors. Indirect TPMS. An indirect TPMS doesn’t have specialized sensors dedicated to monitoring tire pressure.

Direct TPMS measures pressure directly by attaching a sensor within a tire. When the measured pressure is below the threshold value, direct TPMS warns the driver. On the other hand, for vehicles equipped with an Anti-lock Brake System (ABS), indirect TPMS do not require air pressure sensors.
