Understanding Your Car’s Tire Pressure Warning Light

Why Your Car’s Tire Pressure Light is On Despite Proper Inflation

As a responsible car owner, you probably know the importance of taking care of your vehicle. Regular maintenance tasks like changing the oil and checking your lights are crucial to keep your car in good shape. Part of being a responsible driver is understanding the warning lights on your car’s dashboard. One of these warning lights is the TPMS light, which stands for “tire pressure monitoring system.” You might recognize it as the orange tire symbol with an exclamation point in the middle.

When the TPMS Light First Appears

When the TPMS light first comes on, the usual advice is to check the air pressure in each tire. This helps make sure none of your tires are quickly losing air. If you find a tire that’s significantly underinflated, it’s essential to switch it out with your spare tire and get the problem fixed right away. But what do you do if the TPMS light stays on, even when your tire pressure seems fine? Let’s explore the possible reasons and solutions.

Solving the Mystery

Before getting too worried about a persistent TPMS light, consider that there might be external factors causing it. One common factor is temperature changes. When the weather gets colder, the air inside your tires contracts, making your tire pressure drop. In such cases, the solution is pretty simple: just inflate your tires to the psi (pounds per square inch) recommended by the manufacturer to bring them back to the correct pressure.

However, if your tire pressure remains in the recommended range, but the TPMS light stays on, it could suggest a problem within the TPMS system. Some newer cars with advanced TPMS can show each tire’s exact psi readings. If there’s a sensor issue, these readings may appear as blank spaces, indicating a problem with the sensors.

Understanding TPMS Sensors

Your car’s TPMS system relies on sensors, usually called TPMS sensors, installed inside each wheel. These sensors play a critical role in keeping track of your tire pressure and sometimes even the temperature. When a tire’s pressure drops 25% below the recommended psi, these sensors trigger the TPMS light as a warning sign.

These sensors have batteries that typically last about six to ten years or between 90,000 to 120,000 miles. Unfortunately, you usually can’t replace the batteries in these sensors. So, when dealing with a persistent TPMS light, the best solution is to replace all the sensors. This is important because if one sensor’s battery dies, the others might follow suit soon.

The Cost of Replacing TPMS Sensors

The average cost of replacing TPMS sensors is roughly $300, but the exact cost may vary depending on your car’s make and model. Various factors, like the type of sensors needed and labor costs, can influence the final price.

When you see your TPMS light staying on, there’s no need to panic. Understanding the possible reasons and solutions can help ease your worries. Whether it’s a simple adjustment due to temperature changes or a more complicated sensor problem, addressing it promptly ensures your car stays safe and reliable. If your TPMS light remains on continuously, it’s a good idea to consult a qualified technician to diagnose and fix the issue, ensuring your car performs well, and you have peace of mind while driving.
