Common Causes of Tire Pressure Light Blinking

The TPMS light on your dashboard serves as a warning system, alerting you to issues that could potentially affect your vehicle’s safety and performance. When this light starts flashing, it’s signaling that there’s a problem that needs your attention.

There are several reasons why your TPMS light might be flashing, and understanding these causes can help you address the issue effectively.

Low Tire Pressure

The most common reason for the tire pressure light blinking is low tire pressure. Tires can lose pressure for a variety of reasons. For example, even a minor puncture can cause a slow, steady leak of air from the tire. Over time, this can lead to significantly low tire pressure, causing the TPMS light to blink.

Seasonal temperature changes can also cause your tire pressure to fluctuate. Cold weather can cause the air inside your tires to contract, leading to lower tire pressure. Conversely, during hot weather conditions, the air inside the tires might expand, leading to a risk of over-inflation.

Even without a puncture or significant temperature changes, tires naturally lose pressure over time. Therefore, it’s essential to establish a regular routine of monitoring your tire pressure and making necessary adjustments.

If your tires are under-inflated, the TPMS light will blink to alert you. Ignoring this warning can lead to poor vehicle handling, increased tire wear, and decreased fuel efficiency.

Dead Battery in TPMS Sensors

Each tire on your vehicle is equipped with a TPMS sensor. It’s also noteworthy that these sensors are dependent on battery power, and much like any other device powered by batteries, they have a defined lifespan.

Over time, the battery in a TPMS sensor can die, causing the sensor to stop functioning. When this happens, the TPMS light on your dashboard may start blinking.

A dead battery in a TPMS sensor is a common issue, especially in older vehicles. The batteries in TPMS sensors typically last around 5 to 10 years, so if your vehicle is within this age range and your TPMS light is blinking, a dead battery could be the culprit.

It’s also worth noting that TPMS sensor batteries are not replaceable. This implies that a dead battery within the sensor necessitates a complete sensor replacement. This should be done by a professional, as the process involves removing the tire from the wheel.

In conclusion, a blinking TPMS light is a warning that should not be ignored. Whether it’s due to low tire pressure or a dead TPMS sensor battery, it’s important to address the issue promptly to ensure your safety on the road.

Issues with the TPMS Sensor

While low tire pressure is a common cause of a blinking TPMS light, sometimes the issue lies not with the tire pressure but with the TPMS sensor itself. While these sensors are designed for longevity and to withstand various conditions, they are not invincible. Damage, wear and tear, or manufacturing defects can cause a sensor to malfunction.

A damaged or malfunctioning sensor may not be able to accurately measure tire pressure, or it may send incorrect readings to the TPMS. This can trigger the blinking tire pressure light, even if your tire pressure is within the recommended range.

Damage to the sensor can occur due to a variety of reasons. For instance, harsh driving conditions, exposure to extreme temperatures, or even an impact from a pothole or curb can damage the sensor. Additionally, corrosion caused by road salt or other chemicals can also affect the sensor’s functionality.

If a malfunctioning TPMS sensor is suspected to be the reason for your blinking tire pressure light, it’s advisable to have a professional inspect and, if needed, replace the sensor. Ignoring a dysfunctional sensor can result in inaccurate tire pressure readings, compromising your vehicle’s safety and performance.

Incorrectly Installed Tire

An incorrectly installed tire can also cause the TPMS light to blink. Proper tire installation entails correctly seating the tire on the wheel and positioning the TPMS sensor accurately. If this isn’t done, the sensor might not be able to accurately read the tire pressure, causing the TPMS light to blink.

Improper tire installation can occur if the tire isn’t accurately aligned with the wheel if it isn’t adequately inflated during installation, or if the tire’s bead doesn’t properly seat on the wheel rim.

If you’ve recently had a new tire installed and your TPMS light is blinking, an incorrect installation could be the cause. In this case, you should take your vehicle back to the service center or mechanic who installed the tire and have them correct the issue.

Failure to Initialize the TPMS

After servicing your tires or replacing the TPMS sensors, the system needs to be initialized or reset. This process allows the TPMS to “learn” the baseline tire pressure for each tire, which it can then use to detect any significant changes in pressure.

If the TPMS isn’t properly initialized after servicing or sensor replacement, it can cause the TPMS light to blink. This is because the system may be working with incorrect baseline pressure information, causing it to signal a tire pressure issue even when the pressure is within the recommended range.

To correctly initialize the TPMS, you must first inflate the tires to their recommended pressure. Then, drive the vehicle at a specified speed for a certain duration. This exact procedure can differ based on the vehicle’s make and model, making it wise to refer to your vehicle’s owner’s manual or seek advice from a professional.

In conclusion, a blinking TPMS light can be caused by a variety of issues, from low tire pressure to sensor malfunctions to incorrect tire installation.
