The TPMS light on your dashboard serves as a warning system, alerting you to issues that could potentially affect your vehicleโs safety and performance. When this light starts flashing, itโs signaling that thereโs 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, itโs 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. Itโs 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.
Itโs 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 itโs due to low tire pressure or a dead TPMS sensor battery, itโs 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 sensorโs functionality.

If this isnโt 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 isnโt accurately aligned with the wheel if it isnโt adequately inflated during installation, or if the tireโs bead doesnโt properly seat on the wheel rim.
If youโve 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 โlearnโ the baseline tire pressure for each tire, which it can then use to detect any significant changes in pressure.
If the TPMS isnโt 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 vehicleโs make and model, making it wise to refer to your vehicleโs ownerโs manual or seek advice from a professional.
