Why Won’T My Low Tire Pressure Light Go Off?

If you’ve inflated your tires to the proper air pressure, but the warning light stays on, you may have a leak or there’s a problem with the TPMS in one or more of your tires. It’s simple enough to check if there’s a leak in a tire. Just use your tire gauge to recheck the air pressure in all your tires.

Why won’t my tire pressure light go off even though pressure is fine?

Resetting Your Tire Pressure Light
If your TPMS light remains on after inflating the tires to the proper pressure, try these steps: Drive the car at 50 mph for about 10 minutes. This should reset the tire sensors, and the next time you start the car the TPMS light should be off.

Why does my car still say low tire pressure after filling tires?

If you’ve added air but the air pressure warning light stays on, there’s a problem with your Tire Pressure Monitoring System or you have a slow leak. Assuming there is no leak in your tire, a lit TPMS warning light indicates a problem with a tire pressure sensor.

How do I get my low tire pressure light to go off?

After the tires are properly inflated, the light goes off on its own. If it remains on, below are the actions you can take to reset the tire pressure light: Drive at or above 50 mph to reset the sensor for 10 minutes. This can cause your sensor to reset the next time you turn on the car.

Is it OK to drive with TPMS light on?

It’s not safe to drive around with your TPMS light illuminated. Without a tire inspection, there’s no way of knowing how quickly air is leaving your tire, or for how long it has been over or underinflated. The best course of action is to use a tire pressure gauge to check the current inflation level of each tire.

Why wont my tire pressure light turn off even after I reset it?

If you’ve inflated your tires to the proper air pressure, but the warning light stays on, you may have a leak or there’s a problem with the TPMS in one or more of your tires. It’s simple enough to check if there’s a leak in a tire. Just use your tire gauge to recheck the air pressure in all your tires.

Will tire pressure reset itself?

You should only attempt to reset the light after first addressing the tire pressure in every tire. Once your tires are at the appropriate pressure, the light may go off on its own. If it doesn’t go off right away, driving at 50 mph for about 10 minutes should help the tire pressure sensor reset.

Will tire pressure go back to normal?

While the air pressure in your tires may come back to normal when the temperature increases, you shouldn’t ignore low air pressure in your tires. When it gets colder outside, your tires lose about 1 PSI (pounds per square inch) for every 10 degrees that the temperature drops.

What happens if you ignore TPMS?

Driving Through A TPMS Warning Light
The light indicates that the pressure is below the safe levels. Ignoring the warning and driving with low-pressure tires causes them to flex more. It generates excess heat that overheats the tire components and causes them to wear and tear.

Can I ignore the TPMS light?

Why You Should Never Ignore the TPMS Warning Light. An underinflated tire–even minimally–can fail and endanger your safety. For example, underinflation causes tires to flex more, generating more heat. Under these conditions, other components inside the tire can overheat and break down.

Is TPMS expensive to fix?

How much does it cost to replace a TPMS sensor? In the event TPMS sensors need to be replaced, the cost can range from approximately $50-$100 each depending on vehicle type.

How long does it take for a tire pressure light to reset?

Drive at or over 50 mph for about 10 minutes or more. This will generally reset your flashing tire pressure light, which you should notice the next time you turn on your car.

Why is my tire pressure gauge still on?

When the TPMS light comes on – and stays on – at least one of your tires is at a low pressure level. Check the pressure of all of the tires with a gauge and determine the cause of pressure loss and add air or service the tire(s) as appropriate.

Is 31 tire pressure too low?

Technically, any PSI below the recommended number is too low. However, most consider a variance of more than ten percent to be too low. For a car requiring tire inflation to 35 PSI, a reading of 31 or 32 PSI is considered underinflated.

What TYRE pressure is dangerously low?

The absolute lowest tire pressure you can drive on is 20 psi—and even that isn’t recommended. Anything below 20 psi is considered a flat tire, and driving on it can damage your car. If your tires are this low, you should add air. Recommended tire pressures usually range between 32 psi and 35 psi.

How long can you drive with TPMS light on?

If the tire pressure is nominal and there are no leaks, but the TPMS warning light is still on, you could attempt driving for at least 10 minutes at over 30mph to warm the car up and wait for the warning light to turn off.

How do I know if my tire pressure sensor is broken?

After starting a vehicle, a TPMS icon will turn on for a few seconds; however, if it stays on, it indicates that one or more of the tires on the vehicle are at least 25% below the recommended pressure. If the light flashes for approximately one to two minutes, it indicates there is a malfunction in the TPMS system.

Do tire shops change TPMS sensors?

Sometimes, a TPMS alert means one or more of the TPMS sensor batteries has died. In this situation, you may need to replace the TPMS sensor. All of our store locations can perform these replacement services for you.

Do I have to replace all 4 TPMS sensors?

If a single sensor has reached the end of its lifespan, it is highly recommended to replace all sensors at the same time. Similar to headlights, once one sensor dies, the rest are likely to be close behind. The same is true for a corroded valve stem or other non-impact sensor replacement.

Does tire pressure change after driving?

The inflation pressure in tires generally drops by 1 to 2 psi for every 10 degrees the temperature lowers. Also, when you drive your car, and the tires warm up, the pressure in the tires will increase one psi during each five-minute interval in the first 15 to 20 minutes you drive.

Can tires pop from low pressure?

A tire blowout is the most dangerous risk associated with low tire pressure. With more of the tire’s surface touching the road and warming up the rubber, this can cause the tire to overheat and blowout. Tire blowouts happen suddenly and cause the driver to lose control of the vehicle.
