The tire pressure light blinking in a dashboard indication when one or more tires have low air pressure. Low tire pressure is detected by the TPMS (Tire Pressure Monitoring System), which provides PSI readings for each tire.
This mechanism maintains the safety of both the vehicle and the driver. When your dashboard shows the tire sensor light on, it is a warning sign to check the air pressure in your car’s tires. The mechanic guide is here for you .
Why Does the Tire Pressure Light Come On?
There are various reasons why the low tire pressure warning light appears. We’ll find out more about them in this blog. We will discover what they are. Let’s unveil all of them so that we can determine the reason why the low tire pressure sensor light appears on your dashboard.
Leaking or Puncture
The most common reason is a leakage from the stem valve or a tire puncture. Check them manually by listening for a hissing sound from any tire. This could be one of the reasons why the tire pressure light lights.
Cold Weather
The tire pressure light in cold weather is a common issue. It is because, in low temperatures, the air pressure in the tires contracts. This leads to a loss of air in all the tires or one of them.
Faulty TPMS Sensor
If the TPMS is failing or any one sensor of the TPMS is not working, you may face the issue of a blinking tire pressure light. It happens even when your tires are properly inflated.
Recent Tire Change
Many drivers change the tires without resetting the TPMS. This leads to a tire pressure monitor light that stays on until reset. This is a major problem that car owners face.
Overinflation or Underinflation
Sometimes, the inflating machine can be faulty, causing unequal inflation of the tires. Always remember, improperly inflated tires can trigger the tire pressure light to turn on.
TPMS Battery Failure
Some vehicles have TPMS sensors with batteries in them. Over time, these batteries wear out or become faulty, causing the tire pressure monitoring system light to flash or blink.
How to Reset the Tire Pressure Light ?
You can find the solution to the tire pressure light by following the recommendations given below. Read them carefully and act upon them.
Check and Inflate Tires
Inflate your car tires using a gauge. Check that the tires are inflated as recommended in the user manual. You can check the company’s recommended PSI for each tire from the driver’s door jamb. This step usually solves the tire pressure light issue.
Manually Reset the TPMS
Locate the TPMS in your car using the car manual. Press the reset button after starting the car. Let your car park for ten minutes, then drive your car for a few miles. The blinking tire light should turn off, hopefully.
Disconnect and Reconnect the Battery
If the tire pressures are equally inflated, there is no issue with the TPMS. All tire sensors are stable, but the tire pressure light still won’t turn off, even after a reset. In that situation, you can remove the battery terminals and wait 10 minutes. Then reconnect the terminals. This may remove the flashing tire pressure light.
Check for Sensor Malfunctions
Sometimes, your tire PSI may be normal, but the tire pressure sensor light blinking persists. It may be because of faulty sensors located near the wheels. Check them individually and inspect their battery performance. Replace any faulty sensors.
Seek Professional Help
If the tire pressure light is still blinking, consult a car expert. They may advise a better plan to solve the issue.
