A tire pressure monitoring system or TPMS is an electronic system for monitoring the air pressure in a vehicle tire and automatically transmitting a warning to the driver in the event of an under or over inflated tire. These systems have been legislated to be progressively installed on all new passenger carrying US vehicles and a similar move is taking place worldwide.

The majority of systems use Direct tire sensors which transmit real time tire pressure information to the driver of the vehicle either via either a dashboard display or a warning light. The sensors are physical pressure transducers which are attached to the back of the valve stem or are in a form which is banded to the wheel. The sensors are manufactured by International companies such as Schrader, Siemens, TRW, Pacific, Lear and others. There is no common technical standard for the sensors and the OE's and suppliers have generated a multitude of sensor designs.
The sensors also transmit data such as their unique sensor ID, temperature and pressure, battery life and other diagnostic information. This data is sent to the Engine Control Unit (ECU) or specific receiver on the vehicle. Those vehicles which have graphical displays of the TPMS positions can then show on which wheel there is a problem.
Tire Pressure Monitoring helps drivers to properly maintain their vehicle tires, improves vehicle safety and aid fuel efficiency. The National Highway Traffic Safety Administration (NHTSA) in the US has estimated that 533 fatalities per annum are caused by tire defects in road accidents. Adding TPMS to all vehicles could avoid 120 of the 533 yearly victims and save as many as 8,400 injuries every year. Sécurité Routière (the French Institution for Road Safety) estimates that 9% of all fatal road accidents are attributable to tire under-inflation and the German DEKRA estimated that 41% of accidents with physical injuries are linked to tire problems. Tires leak air naturally and over a year a typical new tire can lose between 3 and 9 psi. As most drivers only check their tires at service intervals and when problems occur there is significant scope for fuel savings and efficiencies.
Given this background the US Federal government has legislated for the mandatory use of TPMS. The TPMS mandated by the US law must warn the driver when a tire is under-inflated by as much as 25%.
There is no common standard for the TPMS sensors with variations including frequencies, modulations, data structure, communications protocols, mechanical fitment and many other factors.
When TPMS is installed and tested in the car plant by Bartec the process includes:
Similarly the car dealer or tire shop needs to have a portable TPMS tool available to test the TPMS and read the wheel sensor ID and program the car's ECU in the event of TPMS battery failure, broken sensor/valve, or other repair or replacement of wheels and sensors for custom wheels, winter tires, tire rotation etc. The tool needs to be able to turn out the TPMS warning light.

Tires are one of the important components of a car, and the main consideration for their performance is tire pressure. Too low or too high tire pressure will affect the performance of the tire, and even affect driving safety.
TPMS stands for Tire Pressure Monitoring System. TPMS will monitor tire pressure in real time when you driving, and real-time alarm of air leakage and low tire pressure to ensure driving safety.
The Foxwell TPMS Service Tools allow you to reset, reprogram or activate the TPMS sensors after replacing and adjusting the sensors so that the ECU can accurately read the current tire pressure.
Why Do You Need A Foxwell TPMS Service Tool?
1. Ensure Driving Safety
When your tires are underinflated, the maneuverability of your tires is reduced, especially during tight turns and quick stops. These bad effects start even before the TPMS light comes on. TPMS reset tools allow you to find and fix problems before they become serious.
2. Improve Fuel Efficiency
When tire pressure is too low, the vehicle needs to consume more gas to keep the car moving forward. With the help of the TPMS reset tools, tire pressure can be kept at the correct level to maximize fuel efficiency.
3. Save Money and Time
Without TPMS reset tools, you'll need the help of a mechanic to maintain tires and sensors. When you have a tire pressure reset tool, you can reset your sensors without professional assistance, saving you a lot of time and money.
What Can Foxwell TPMS Service Tools Do?
1. Read TPMS Data
The TPMS tool can obtain TPMS sensor data including pressure level, tire temperature, battery level, sensor ID, etc.
2. Diagnosis TPMS System
If the TPMS error light comes on due to low tire pressure, changing tires, tire rotation, or switching from summer tires to winter tires, you can use the TPMS reset tool to turn it off.
3. TPMS Sensor Relearning
After replacing or adjusting the sensor, the Foxwell TPMS service tool will "tell" the engine control module the new location of the tire pressure sensor. Foxwell TPMS service tool allows you to relearn 98% of sensors.
4. TPMS Sensor Programming
While relearning will tell the ECM how to find the sensor, the sensor still needs to be programmed with the necessary protocols/applications to make the new sensor fully compatible with the vehicle's ECM.
5. TPMS Sensor Activation
You can use the TPMS service tool to activate a TPMS sensor to start collecting and transmitting information. The Foxwell TPMS service tool activates 99% of the sensors on the market.
Foxwell TPMS tools are known for their speed, reliability and customer service. Foxwell TPMS service tools are a smart investment for car enthusiasts and mechanics. Foxwell TPMS tools accurately read tire pressure data, monitor and reset tire pressure systems, helping you stay safe on the road.
