If your TPMS light (Tire Pressure Monitoring System) comes on, it’s important to take action quickly. The TPMS is designed to alert you when your tire pressure is low or there is an issue with your tires, which can affect your vehicle’s safety and performance. In this article, we’ll explore the causes of a TPMS warning light, steps to take when it activates, and tips for maintaining proper tire pressure to ensure safe driving.
What is the TPMS Light and How Does It Work?
The TPMS light on your dashboard is an indicator that monitors the air pressure inside your vehicle’s tires. It typically lights up when tire pressure falls below the recommended level. Modern vehicles come equipped with either a direct TPMS or an indirect TPMS.
- Direct TPMS: Uses sensors inside each tire to measure air pressure and send data to the vehicle’s computer.
- Indirect TPMS: Measures tire pressure through wheel speed sensors and estimates pressure based on the rotation of the tires.
When the light turns on, it’s a warning that something needs attention—either low pressure, a sensor issue, or another potential tire problem.
Common Causes of TPMS Light Activation
There are several reasons why your TPMS warning light might turn on. Some of the most common causes include:
- Low tire pressure: This is the most common reason for the TPMS light to activate.
- Temperature changes: Cold weather can cause tire pressure to drop, triggering the light.
- Tire damage or punctures: A hole or puncture in the tire can lead to a slow air leak, activating the light.
- Faulty TPMS sensor: Sometimes, the issue is not with the tires but with the sensor itself.
- Incorrect tire pressure after a tire change: If the TPMS light comes on after a tire replacement or rotation, it could indicate improper tire pressure.
- Overinflated tires: Excessive tire pressure can also cause the TPMS light to activate.
Steps to Take When Your TPMS Light Comes On
If the TPMS light appears on your dashboard, it’s essential to take the following steps to ensure your tires are in good condition.
Step 1: Check Tire Pressure
The first thing to do is check the pressure of your tires. You can use a tire pressure gauge to measure the air pressure and compare it to the recommended levels specified in your vehicle’s manual or on the tire placard (usually located inside the driver’s side door frame). If the tire pressure is low, inflate the tire to the correct pressure.
Step 2: Inspect Tires for Damage or Punctures
If your tire pressure is normal, visually inspect each tire for signs of damage, such as cuts, bulges, or punctures. Even small punctures can cause slow leaks, leading to a drop in tire pressure. If you spot a nail or screw, it’s best to take your car to a professional to have the tire patched or replaced.
Step 3: Reset Your TPMS System
In some cases, the TPMS light may stay on even after you’ve corrected the tire pressure. If this happens, your vehicle’s TPMS system may need to be reset. Check your owner’s manual for the correct procedure, as the reset method can vary depending on the make and model of your car. In many cases, you can reset the TPMS by driving for a short period of time or by using the TPMS reset button located near the steering wheel or dashboard.
Step 4: Get Professional Help
If your tire pressure is correct, and you’ve inspected the tires for damage but the light remains on, there may be an issue with the TPMS sensors themselves. Faulty or damaged sensors may need to be replaced. If you’re unsure of the issue, it’s best to take your vehicle to a certified mechanic for further diagnosis and repair.
The Importance of Proper Tire Maintenance
Maintaining the correct tire pressure is essential not only for safety but also for prolonging the life of your tires and improving fuel efficiency. Underinflated tires can cause uneven wear, reduced handling, and lower gas mileage, while overinflated tires can lead to a higher risk of a blowout.
To avoid problems, make it a habit to check your tire pressure at least once a month and before long trips. Regularly inspect your tires for signs of damage and replace them when necessary.
