Quality TPMS sesors

 What is TPMS?

Direct TPMS is a warning system that warns a vehicle's operator of an unsafe change in the air pressure in one or more of the tires. Readings are provided by pressure sensing transmitters mounted inside each tire and sent to a central computer (ECU) for display on the dashboard. A warning indicator light on the instrument panel and an audible warning notify the driver if a *5% drop in pressure occurs.

How do I know if my vehicle is equipped with TPMS? 

In the U.S., if you purchased a car or light duty vehicle under *0,**0 lbs, manufactured after September 1, ***7, you have TPMS. If your model was manufactured after October 5, ***5, you may have TPMS. Also, prior to the legislation, some higher-end vehicles also came equipped with TPMS as a premium option. Among other matters, within TREAD Act of ***0, the U.S. federal government mandated the required implementation of TPMS on all new vehicles in the following phased rollout:

 
•*0% of new vehicles from Oct 5, ***5–Aug *1, ***6
•*0% of new vehicles from Sept 1, ***6–Aug *1, ***7
•**0% of new vehicles from Sept 1, ***7 and beyond

There are several ways to determine if your vehicle is equipped with TPMS. The easiest include checking the owner's manual and watching the dashboard indicator lights at startup. Turn the vehicle ignition switch to the "ON" or "AUX" position, or simply start the vehicle.

What are the TPMS types?

Direct TPMS measures the actual pressure from within the tires, using a pressure sensor with a transmitter. An in-car receiver monitors the pressure, and notifies the driver if the pressure in any tire drops below a set level.

Indirect TPMS monitors tire pressure by using the vehicle's antilock braking system's wheel speed sensors. The system compares the rotation of the tires to one another, and will alert the system if one tire rotates at a different speed than the others. Because the system is indirect, it may trigger more false alerts.
