Sensor Problems

Road dirt and debris can accumulate around the sensors, which may result in their malfunctioning. Potholes can also cause damage to the sensors by shaking them out of place or causing internal damage. Corrosion over time due to exposure to moisture or salt on the roads can significantly impact sensor functionality.

It is not uncommon for sensors to go missing after a wheel change or tire rotation. During these procedures, if properly secured, the sensors may be able to avoid being dislodged and accidentally left behind at the service location. It leads to a missing sensor, which must be replaced in order to ensure proper tire pressure monitoring.

If you notice that your tire pressure light is blinking on your vehicle’s dashboard, it might indicate a need for battery replacement in one or more of your TPMS sensors. The blinking light indicates that the system has detected low battery voltage in one or more of its sensors.

The typical lifespan of TPMS sensor batteries ranges from 5-7 years before they require replacement. Over time, the battery’s performance degrades, resulting in insufficient power supply to maintain accurate readings and transmit signals effectively.

Low tire pressure

Maintaining proper tire pressure is essential for optimal vehicle performance, fuel efficiency, and safety. When tires are underinflated, their ability to grip the road decreases, causing poor handling and longer braking distances. Low tire pressure can lead to increased tire wear and decreased fuel efficiency. To determine if your tires are underinflated, you can use a gauge to measure the pressure levels. 

If the gauge indicates significantly low pressure, simply using an inflator may only provide a temporary solution, as there might be an underlying issue causing the deflation. In such cases, it is recommended to replace the underinflated tire with a properly inflated spare tire for improved performance and safety on the road.

Temperature Change

In cold weather conditions, it is common for tire pressure to decrease. It is crucial to regularly monitor the tire pressure to ensure optimal performance and safety while driving. To accurately measure the tire pressure, it is recommended to use a reliable and accurate gauge specifically designed for this purpose.

If you notice that the tire pressure is low, taking prompt action becomes essential. One option is to visit a nearby gas station where they typically offer air pumps for public use. Alternatively, investing in a portable compressor can provide convenience and flexibility as it allows you to inflate your tires at any time and location.

Why Is My Tire Pressure Light On When My Tires Are Fine?

There are many reasons why your tire pressure light may be on, even when your tires seem to be fine. One possible explanation is that the tire pressure sensor itself may be malfunctioning. Over time, these sensors can become less accurate or even fail, causing the light to illuminate when there is no actual issue with your tire pressure. But we will discuss it one by one to get a sensible answer.

Why Is My Tire Pressure Light On When My Tires Are Fine?

Cold Temperature

One common culprit is the cold temperature. As the temperature drops, so does the air pressure inside your tires. It can trigger the tire pressure monitoring system (TPMS) and cause the light to illuminate. For every 10-degree Fahrenheit drop in temperature, your tire’s air pressure can decrease by about 1 psi (pound per square inch).

The tire was recently fixed

If you’ve recently fixed your tire and find yourself scratching your head as to why the tire pressure light is still on, there could be a few reasons for this perplexing issue. One possibility is that the wheel alignment may have been affected during the repair process. When the tire is taken off and put back on, it’s important to ensure that everything aligns properly. If not, it can result in uneven pressure distribution and trigger the tire pressure monitoring system.

Another factor to consider is that sometimes when fixing a tire, the position of the sensors can get disturbed. The sensors play a vital role in detecting any changes in tire pressure and transmitting this information to your vehicle’s computer system. If they are not repositioned correctly after a repair, they may mistakenly show that there is low pressure even when your tires are actually fine.

Sensors are damaged

When driving at high speeds, it is important to be cautious of bumps and potholes on the road. These obstacles can cause damage to the sensors in your vehicle, particularly the Tire Pressure Monitoring System (TPMS). The impact of hitting a bump or pothole at high speeds can burden these sensors, potentially leading to malfunctioning or inaccurate readings.

Harsh braking or abrupt acceleration can also put stress on these sensors. Such sudden changes in speed can affect the internal components of the TPMS, disrupting its ability to monitor tire pressure accurately.

The sensor battery is dead.

The batteries in tire pressure sensors are designed to last an average of 5 to 10 years, depending on various factors such as usage and climate conditions. When these batteries die, they can no longer transmit signals to the car’s computer system, causing the tire pressure light to illuminate.

Faulty Wheel Speed Sensors

Faulty wheel speed sensors are responsible for measuring the rotational speed of each wheel and sending signals to the vehicle’s computer system. Various factors, such as exposure to extreme temperatures, dirt, debris buildup, or electrical failures, can cause faulty wheel speed sensors.

 Sometimes, these sensors may need to be replaced to resolve the issue. Pay attention to this warning light even if your tires are properly inflated because incorrect tire pressure readings can affect your vehicle’s handling and overall safety.

Low Pressure in Spare Tire

Another reason can be due to low pressure in your spare tire. While it may not seem obvious initially, spare tires can also come equipped with a TPMS (Tire Pressure Monitoring System) sensor. This sensor is responsible for detecting changes in tire pressure and alerting the driver through the dashboard light.

You should buy a good company tires like Michelin, Bridgestone, Continental and Goodyear. Its one time investment that secure your life and you can feel free to travel from one place to another place.

Why Is My Tire Pressure Light Still On After Filling Tires?

If your tire pressure light is still on even after filling your tires, it could be an indication that one of your tires is leaking air. While filling the tires with air might temporarily solve the issue by increasing the pressure, it doesn’t address the underlying problem of a possible leak. In such cases, using a tire pressure gauge can provide you with valuable insights into identifying which tire is causing the issue.

It’s important to realize that the tire pressure light may just need a reset.
