Tire Pressure Monitoring System (TPMS)
1. What is a Tire Pressure Monitoring System (TPMS)?
Modern automobiles are equipped with advanced safety features, including Tire Pressure Monitoring Systems (TPMSs). These systems monitor the air pressure in each tire in real-time, providing drivers with a crucial warning when a tire is under-inflated. Under-inflation can compromise vehicle handling, fuel efficiency, and tire life. TPMSs are designed to detect gradual leaks or sudden tire damage, ensuring that drivers are aware of potential hazards and can take prompt action.
There are two main types of TPMSs: indirect and direct.
Indirect TPMSs utilize the vehicle’s anti-lock braking system (ABS) sensors to monitor wheel rotation speed. When a tire is under-inflated, its circumference decreases, causing it to rotate faster than the other tires. The ABS sensors detect this difference in rotation speed and trigger a warning light on the dashboard.
Direct TPMSs use individual pressure sensors mounted inside each tire. These sensors transmit real-time pressure data to a central receiver in the vehicle. Direct TPMSs provide more accurate and precise tire pressure readings and can alert drivers to specific tire positions that are under-inflated.
| Type | Advantages | Disadvantages |
|---|---|---|
| Indirect TPMS | Less expensive No need for additional components |
Less accurate Can’t display individual tire pressures |
| Direct TPMS | More accurate Displays individual tire pressures |
More expensive Requires additional components |
2. How does a TPMS work?
TPMSs operate through a series of sensors and a central receiver. The sensors, located either inside the tires (direct TPMS) or within the ABS system (indirect TPMS), monitor tire pressure and transmit data wirelessly to the receiver. The receiver then processes the information and displays it on the dashboard or multi-information display.
3. What are the benefits of a TPMS?
TPMSs offer numerous benefits, including:
- Improved safety: Under-inflated tires can reduce vehicle stability and handling, increasing the risk of accidents.
- Extended tire life: Proper tire pressure prolongs tire life by ensuring even wear and preventing premature failure.
- Increased fuel efficiency: Under-inflated tires increase rolling resistance, resulting in higher fuel consumption.
- Convenience: TPMSs eliminate the need for manual tire pressure checks, saving time and effort.
Dashboard Indicators
The dashboard indicators are designed to provide drivers with information about the status of their tires. These indicators can be used to check tire pressure, as well as to identify other issues related to the tires or tire pressure monitoring system. There are two main types of dashboard indicators, which can be classified by their symbols and any accompanying notifications.
Tire Pressure Monitoring System (TPMS) Indicator
The TPMS indicator is a yellow light on the dashboard that looks like a horseshoe with an exclamation mark in the center. This light will illuminate when the tire pressure in any of the tires is below the recommended level. TPMS also provides auditory notification in some vehicles, generally in the form of a chime or verbal alert. This alerts drivers to the condition and gives them the opportunity to address a potential issue before it becomes a hazard.
| Tire Pressure | TPMS Indicator |
|---|---|
| Normal | No light or notification |
| Low tire pressure | Yellow horseshoe with exclamation mark lights up, possible chime or notification may sound |
| Flat tire | Yellow horseshoe with exclamation mark flashes rapidly, chime or notification sounds repeatedly |
Step-by-Step Guide to Checking Tire Pressure

* Refer to the vehicle’s owner’s manual for specific tire pressure recommendations.
By following these steps and additional tips, you can ensure that your tires are properly inflated and performing at their best.
Monitoring Indirect TPMS
Indirect TPMS, as mentioned earlier, measures tire pressure indirectly by monitoring their rotational speeds. It utilizes wheel speed sensors, which are usually part of the anti-lock braking system (ABS) or traction control system, to detect changes in tire pressure.
When tire pressure drops, the affected tire’s diameter decreases, resulting in a slight increase in its rotational speed. This variation in speed is detected by the wheel speed sensor and reported to the TPMS module. The module then calculates and displays the estimated tire pressure on the dashboard.
Understanding the Dashboard Display
Indirect TPMS typically uses a combination of lights and symbols on the dashboard to indicate tire pressure status:
| Indicator Light | Meaning |
|---|---|
| Amber or Red TPMS Warning Light | Indicates low tire pressure in one or more tires. |
| Tire Pressure Display | Displays the estimated tire pressure for each tire, typically in pounds per square inch (psi) or kilopascals (kPa). |
The specific indicators and display format may vary depending on the vehicle make and model. Consult your owner’s manual for detailed information.
