1. Understanding the Tire Pressure Monitoring System (TPMS)

What is the Tire Pressure Monitoring System (TPMS) and how does it work?

The Tire Pressure Monitoring System (TPMS) is an electronic system in your vehicle that monitors tire air pressure and alerts you when it falls below a certain level. According to the National Highway Traffic Safety Administration (NHTSA), TPMS has significantly reduced tire-related accidents. There are two main types of TPMS: direct and indirect. A direct TPMS uses pressure sensors inside each tire to measure pressure directly, while an indirect TPMS estimates tire pressure by monitoring the wheel’s rotational speed.

1.1. Direct TPMS

How does a direct TPMS work?

Direct TPMS uses pressure sensors mounted inside each tire to measure the real-time tire pressure. As explained by experts at CARDIAGTECH.BIZ, these sensors transmit data to the vehicle’s central computer, which displays the tire pressure on the dashboard or alerts the driver if the pressure is too low. According to a study by the Society of Automotive Engineers (SAE), direct TPMS provides more accurate and immediate pressure readings than indirect systems. Direct TPMS provides real-time pressure readings directly from sensors in each tire.

1.2. Indirect TPMS

How does an indirect TPMS work?

Indirect TPMS works by monitoring the speed of each wheel using the vehicle’s anti-lock braking system (ABS). CARDIAGTECH.BIZ notes that if a tire loses pressure, its rolling radius decreases, causing it to spin faster than other wheels. The system detects this difference and alerts the driver. According to a report by the National Research Council, indirect TPMS requires calibration after tire inflation or rotation to ensure accuracy. Indirect TPMS monitors wheel speed to estimate tire pressure, using the ABS system.

1.3. TPMS Components

What are the key components of a TPMS?

The key components of a TPMS include:

• Pressure sensors (for direct TPMS).
• A central processing unit (CPU).
• A dashboard display.
• Wheel speed sensors (for indirect TPMS).

CARDIAGTECH.BIZ emphasizes that these components work together to provide accurate and timely information about tire pressure, enhancing vehicle safety. A study published in the “Journal of Transportation Safety & Security” highlights the importance of regular TPMS maintenance to ensure optimal performance. Regular maintenance of TPMS components is crucial for optimal performance.

2. Identifying the Reasons Why Your TPMS Light is On

Why is my TPMS light illuminated?

There are several reasons why your TPMS light may be on. Common causes include low tire pressure, temperature changes, sensor malfunction, or a dead sensor battery. As noted by automotive experts at CARDIAGTECH.BIZ, identifying the specific cause is the first step in resolving the issue. According to a survey by the Tire Rack, low tire pressure is the most frequent reason for TPMS alerts. Low tire pressure, sensor malfunction, or temperature fluctuations are common triggers.

2.1. Low Tire Pressure

How does low tire pressure trigger the TPMS light?

Low tire pressure causes the tire to have a smaller rolling radius, which can be detected by both direct and indirect TPMS systems. CARDIAGTECH.BIZ explains that when the pressure drops below the recommended level, the TPMS light illuminates to alert the driver. The Rubber Manufacturers Association reports that properly inflated tires improve fuel efficiency and extend tire life. Low tire pressure reduces rolling radius, triggering the TPMS alert system.

2.2. Temperature Changes

Can temperature changes affect tire pressure and trigger the TPMS light?

Yes, temperature changes can significantly affect tire pressure. As the temperature drops, air pressure in the tires decreases, and vice versa. CARDIAGTECH.BIZ advises that a decrease of 10 degrees Fahrenheit can lower tire pressure by 1-2 PSI. According to research from the U.S. Department of Energy, maintaining proper tire pressure in all weather conditions is essential for fuel efficiency. Temperature variations can lower tire pressure, leading to TPMS warnings.

2.3. Sensor Malfunction

What are the signs of a TPMS sensor malfunction?

Signs of a TPMS sensor malfunction include a continuously lit TPMS light, inaccurate pressure readings, or a failure to reset the TPMS after inflating the tires. CARDIAGTECH.BIZ recommends that if you suspect a sensor malfunction, have it checked by a professional.
