What does TPMS mean?
Types of TPMS
Tire pressure monitoring system is also called "TPMS". By recording the tire speed or the electronic sensor installed in the tire, it can automatically monitor the various conditions of the tire in real-time. The monitored data includes pressure, tire temperature, battery status, etc. This technology can provide safe and effective guarantees for vehicle driving.
How indirect TPMS and direct TPMS work?
Indirect tire pressure monitoring system
Direct Tire Pressure Monitoring System
Tire pressure monitoring system: advantages and disadvantages
Tire pressure monitoring systems can be divided into two types: indirect tire pressure monitoring systems and direct tire pressure monitoring systems.Tire air pressure and temperature are measured by pressure sensors installed inside each tire. Then, the sensors transmit the data to the vehicle's on-board computer via a wireless transmitter. When the tire has high pressure, low pressure or high temperature, the system will send a warning to the owner. And the range of the tire pressure warning value and the temperature warning value can be set by the car owner according to the vehicle model, car habits, and geographical location. Direct TPMS provides accurate and real-time tire pressure data. making it a more reliable system.Tire pressure is calculated indirectly via wheel speed sensors and other data from the vehicle's anti-lock braking system (ABS). Indirect TPMS does not require pressure sensors in each tire, and while this makes it a more affordable system, it does not provide as accurate data as direct TPMS and may not be able to detect gradual tire pressure loss.When tire pressure is reduced, the weight of the vehicle makes the tire smaller in diameter, causing it to spin faster than other tires. Wheel speed sensors detect a change in vehicle speed and send a signal to the vehicle's Electronic Control Module (ECM). The ECM then determines which tire is low on pressure by comparing the wheel speed signals. If one tire is spinning faster than the others, it assumes that tire is low on pressure and sends a warning signal to alert the driver.The direct tire pressure monitoring system monitors the tire pressure through the pressure sensor installed in each tire and sends the data to the central control module. The central control module compares the acquired tire pressure data with the tire pressure set by the vehicle. If tire pressure is too high or too low, the system alerts the driver via a warning light on the dashboard or a message on the vehicle's display. The direct TPMS system provides real-time tire pressure monitoring data, allowing drivers to take corrective measures before tire damage occurs.
As a technology for monitoring tire pressure, the tire pressure monitoring system has the following advantages and disadvantages:
Advantages
Disadvantages
' Extended Tire Life: Uneven tire wear has a lot to do with over- or under-inflation of the tires. A TPMS helps determine if a tire is properly inflated, which helps extend the life of the tire without causing it to fail prematurely and result in costly repairs.' Improved Fuel Efficiency: When tires are inflated to the correct pressure, fuel efficiency is improved. Because underinflated tires lead to increased rolling resistance and lower fuel economy.' Reduced Environmental Impact: Properly inflated tires help reduce the amount of fuel used by the vehicle, which helps reduce the amount of greenhouse gas emissions the vehicle produces.' Improved overall safety: By monitoring tire pressure, drivers can be alerted to potential tire problems and corrective action can be taken before a tire blowout or other dangerous situation occurs. This helps improve road safety.' Expensive: TPMS can be expensive to install. Additionally, TPMS requires regular maintenance to keep it functioning properly, which may include replacing batteries, sensors or other components.' Error reminder: TPMS systems provide false alarms when sensors are damaged or malfunctioning. This can lead to driver frustration and the risk of ignoring genuine warnings.' Limited range: TPMS sensors have a limited range, which means they may not be able to monitor tire pressure on vehicles that are towing a trailer or traveling long distances.The TPMS (Tire Pressure Monitoring System) Scan Tool

The purpose of the tire pressure monitoring system (TPMS) in your vehicle is to warn you that at least one or more tires are significantly under-inflated, possibly creating unsafe driving conditions. The TPMS low tire pressure indicator is a yellow symbol that illuminates on the dashboard instrument panel in the shape of a tire cross-section (that resembles a horseshoe) with an exclamation point.
That indicator light in your vehicle has a history. It's a history rooted in years of uncertainty about proper tire pressure and many serious car accidents that might have been avoided had drivers known their air pressure was low. Even now, it's estimated that a substantial number of vehicles hit the road each day with underinflated tires. However, proper tire maintenance with the aid of a TPMS can and does help prevent many serious accidents.
Before this indicator light became commonplace, knowing whether your air pressure had reached unsafe levels meant getting out, crouching down, and using a tire gauge. With few exceptions, this was the only pressure-checking tool ordinary consumers had at their disposal.
Then, in response to a surge in accidents due to underinflated tires, the US government passed the Transportation Recall Enhancement, Accountability, and Documentation (TREAD) Act. One of the outcomes of this legislation is that most vehicles sold in the United States since include a tire pressure monitoring system of some kind.
Not every TPMS works the same way. The illumination of the low tire pressure indicator represents the final step in the process of either an indirect TPMS or a direct TPMS.
An indirect TPMS typically relies on wheel speed sensors that the anti-lock brake system uses. These sensors measure the rate of revolution each wheel is making and can be used by on-board computer systems to compare with each other and to other vehicle operation data such as speed.
Based on the rate of revolution of each wheel, the computer can interpret the relative size of the tires on your vehicle. When a wheel starts spinning faster than expected, the computer calculates that the tire is underinflated and alert the driver accordingly.
So, an indirect tire pressure monitoring system doesn't actually measure tire pressure. It's not electronically processing the same kind of measurement you might see with a tire gauge. Instead, an indirect tire pressure monitor simply measures how fast your tires are rotating and sends signals to the computer that will actuate the indicator light when something in the rotation seems amiss.
-- Relatively inexpensive compared to a direct TPMS
-- Requires less programming/maintenance over the years than a direct TPMS
-- Less overall installation maintenance than its direct counterpart
-- May become inaccurate if you purchase a bigger or smaller tire
-- May be unreliable when tires are unevenly worn
-- Must be reset after properly inflating every tire
-- Must be reset after routine tire rotation
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. The direct tire pressure monitoring system sends all of this data to a centralized control module where it's analyzed, interpreted, and, if tire pressure is lower than it should be, transmitted directly to your dashboard where the indicator light illuminates. A direct tire pressure monitor usually sends all of this data wirelessly. Each sensor has a unique serial number. This is how the system not only distinguishes between itself and systems on other vehicles, but also among pressure readings for each individual tire.
Many manufacturers use proprietary technology for these highly specialized systems, so replacing a TPMS in a way that's consistent and compatible with your vehicle will require an experienced, knowledgeable technician.
-- Deliver actual tire pressure readings from inside the tire
-- Not prone to inaccuracies because of tire rotations or tire replacements
-- Simple resynchronization after tire rotation or tire replacements
-- Batteries inside the sensors usually last for about a decade.
-- May be included in a vehicle's spare tire
-- More expensive overall than an indirect TPMS
-- Though simple, resynchronization may require costly tools.
-- Battery rarely serviceable; if the battery is drained, the whole sensor must be changed.
-- Proprietary systems make installation, service, and replacement confusing for consumers and auto shops.
-- Sensors are susceptible to damage during mounting/demounting
Although the methods may be different, both systems serve the same purpose and activate the same indicator light. Even though a TPMS can deliver accurate alerts when properly maintained, it's not a replacement for manual air pressure checks, consider it just another item in your car maintenance toolbox.
