Understanding TPMS Sensor: What It Is and How It Works

TPMS Sensor: A Comprehensive Guide for Vehicle Owners In India

A TPMS (Tyre Pressure Monitoring System) sensor is a small device installed in each vehicle tyre to monitor air pressure. A TPMS sensor signals the vehicle’s system when the tyre pressure drops below a certain level.

It’s essential for vehicle safety because proper tyre pressure is critical for safe driving. An underinflated tyre can affect the vehicle’s handling, reduce fuel efficiency, and even cause a tyre blowout. TPMS sensors help prevent these issues by alerting drivers when a tyre is low on air, allowing them to take action before serious problems occur.

There are two main types of TPMS sensors: direct and indirect. Direct TPMS sensors use pressure sensors inside the tyres to measure the air pressure, while indirect TPMS sensors use the vehicle’s anti-lock brake system to calculate tyre pressure based on the rotation speed of each wheel. Direct TPMS sensors are generally considered more accurate but can be more expensive to install and maintain.

The guide aims to educate vehicle owners on the benefits of using TPMS sensors, how to choose the right type for their vehicle, and how to maintain them properly.

How TPMS Sensor Works

TPMS sensors are installed in each tyre and utilize a wireless sensor to send data to a smart tyre app. The app can alert drivers about low pressure via a Bluetooth sensor. Whenever the pressure falls below the recommended level, the sensor informs the monitoring system, and a warning light is displayed on the dashboard. The app can predict the expected pressure and generate alerts for any significant deviations.


TPMS Sensor Maintenance

Proper maintenance of TPMS sensors is important to ensure they function correctly and provide accurate readings. The following are some key maintenance tasks:

Regular Inspection: Inspect TPMS sensors regularly for physical damage, such as cracks or corrosion, especially when changing or rotating tyres.

Battery Replacement: TPMS sensor batteries need replacement every 5 to 7 years, depending on the type and manufacturer.

Sensor Replacement: Replace damaged or malfunctioning TPMS sensors with professional diagnosis and repair.

Calibration: Follow the manufacturer’s recommended calibration procedure after the tyre pressure change to ensure accurate readings and proper functioning of the TPMS system.

Troubleshooting TPMS Sensor Issues

There are several common issues that vehicle owners may encounter with their TPMS sensors, and understanding how to troubleshoot these issues can help prevent further problems. The followings are some common TPMS sensor issues and their solutions:

TPMS Sensor Warning Light

If the TPMS sensor warning light is illuminated, it may indicate low tyre pressure, a malfunctioning sensor, or a communication problem with the vehicle’s computer. Check the tyre pressure in all four tyres, and if the pressure is correct, a professional mechanic should diagnose and repair the issue.

False Readings

It may provide false readings due to a problem with the sensor or a communication issue with the vehicle’s computer. Check the tyre pressure in all four tyres, and if the pressure is correct, a professional mechanic should diagnose and repair the issue.

TPMS Sensor Failure

In rare cases, if a TPMS sensor fails, it must be replaced by a professional mechanic due to issues with the sensor’s battery or internal components.

Choosing the Right TPMS Sensor for Your Vehicle

Choosing the right TPMS sensor for your vehicle involves considering factors such as the sensor type (direct or indirect), compatibility with your vehicle’s make and model, the sensor’s accuracy, and durability. It is important to consult the vehicle’s owner’s manual and consult with a professional mechanic or tyre specialist to ensure you select the correct TPMS sensor for your vehicle. Additionally, it is important to choose a sensor approved by the vehicle manufacturer that meets relevant safety standards.

Upgrading Your Vehicle’s TPMS Sensor


Benefits of Upgrading

Upgrading your vehicle’s TPMS sensor has several benefits, including improved accuracy, increased functionality, and better compatibility with aftermarket wheels and tyres. Some upgraded sensors may provide additional features such as temperature monitoring and advanced diagnostics.

Compatibility Issues

Ensure your TPMS sensor upgrade is compatible with your vehicle’s make and model before installation. Some sensors may require additional components or may not work with certain types of vehicles. Consult a professional mechanic or tyre specialist to find the best upgrade options for your vehicle.

Installation Process

The TPMS sensor installation process varies by sensor type, vehicle make, and model. Some may require professional installation, while others have a simple DIY process that can be done at home with basic tools.

Cost vs. Benefits

Consider the cost vs. benefits before upgrading your TPMS sensor. While upgraded sensors can provide improved accuracy and functionality, they may not be necessary for some vehicles. Consult a mechanic or tyre specialist to determine if the upgrade is necessary for your vehicle and driving needs.

In summary, the TPMS sensor is an essential device that significantly maintains vehicle tyres’ safety and longevity. It helps vehicle owners in India monitor their tyre pressure and take prompt action to prevent accidents or tyre blowouts. Regular maintenance, calibration, and troubleshooting of TPMS sensors can significantly improve the accuracy and reliability of the system. Choosing the right TPMS sensor for a vehicle is crucial, and it is recommended to consult a professional mechanic or tyre specialist. By following the comprehensive guide on TPMS sensors, vehicle owners in India can enjoy safer, more efficient, and worry-free driving.



Q. Why is it essential to maintain proper tyre pressure in vehicles?

A. Proper tyre pressure ensures better fuel economy, improved handling, and longer tyre life. Under-inflated tyres can cause premature wear, decreased fuel efficiency, and handling issues, while over-inflated tyres can lead to blowouts, uneven wear, and a rougher ride.

Q. Can TPMS sensors be installed after purchasing a vehicle without them?

A. Yes, installing TPMS sensors after purchasing a vehicle is possible. Still, it’s important to ensure they are compatible with the vehicle’s make and model and installed and programmed correctly to communicate with the TPMS app. It’s highly recommended to consult a professional mechanic or tyre technician to ensure proper installation.
