What should I do if my tire pressure light is still on?
If the tire pressure light is still on after filling the tires, the light may need to be reset. The process for this varies greatly by car make and model. Sometimes you can find the exact procedure in the owner’s manual or by searching your vehicle online.
Why does the TPMS light come on after new tires?
Two weeks ago I bought 4 new tires form my 2008 Honda Fit Sport, then had an alignment. A week later, the “TPMS” light – not the (!) light indicating low pressure – came on and stayed on.
Why is my tire pressure sensor warning light on?
Disturbed or Tripped Sensor. If you’ve recently had your vehicle serviced and the tire warning light activated immediately or shortly after, it’s likely that something tripped one or more of the tire pressure sensors. Some models require the TPMS to be reset after adding pressure.
How can I reset the TPMS light in my car?
Resetting the TPMS differs from car to car but there are some general techniques which are easy to execute and help in successfully recalibrating the monitoring system. Before you try to reset your TPMS light, you should always make sure that you have the right tire pressure in your vehicle. Use a tire pressure gauge to check the tire pressure.
How does a low tire pressure light work?
The TPMS (or Tire Pressure Monitoring System) uses sensors on the vehicle to determine when a tire has low pressure and alerts the driver with a warning light so the tires can be checked out.
When to use the TPMS light on your tires?
The purpose of the TPMS is to notify the driver whenever one or more tires has low air pressure in them. For instance, let’s say you’re driving over a speed bump too quickly. It could knock some of the air out of your tires. If the tire pressure gets too low, then a TPMS light will illuminate on the dashboard to notify you of this.
Can a spare tire have a tire pressure light?
Not all vehicles have TPMS in the spare tire, but those that do can sneakily throw a tire pressure light when this tire is inevitably forgotten. This is not a bad thing, though; it’s always a good idea to keep the spare inflated properly in case you need it.
Why is my tire light not turning off?
Brought the car back to tire store and the service manager checked the pressure, the tires were all low pressure, 29-30 psi instead of 35s. He re-inflated them all but the tire light will not turn off.
Why is it important to check tire pressure?
For the TPMS tool to work efficiently, it must be on the tire’s rims. If there is a tire change process, the TPMS can get damaged. It is vital to check the pressure light as you change your tire. The batteries that power TPMS sensors have a lifespan of 6 to 10 years. If they become weak, then a signal interruption will occur.

What to do when your tire pressure light comes on?
One or more of your tires has dangerously low pressure. Here are a few scenarios: If you start your vehicle and the TPMS light stays on, don’t drive it. Shut the vehicle off. If you have a system that tells you which tire is affected, get your tire gauge out of the glove box and check that tire’s pressure.
Why is my service tire monitor light stuck?
Common causes of a stuck light include damaged TPMS sensors and incorrect tire pressure. However, some cases may only require the tire pressure system to just be reset.
When to check tire pressure in cold weather?
However, before consulting the mechanic regarding this issue, do check the tire pressure. If the tire pressure is fine, the TPMS needs to be repaired. 2. Extreme Cold Weather Usually, the car tire pressure decreases during the cold weather, even when it’s properly inflated.
Why is there a TPMS warning light on my tire?
The TPMS warning light can sometimes be triggered when there is no problem with your tire pressures. This may be caused by a faulty sensor, located either inside a tire or in the anti-lock braking system. Your mechanic will need to take a look. Run-flat tires are tires that you can drive on for a limited distance after they lose their air pressure.
What’s the best way to reset TPMS warning light?
This might be the easiest method as it requires you to drive your car at 50 mph for about 10 miles, and the sensors will automatically calibrate themselves after you made sure that the tires have the right tire pressure. Some vehicles require a higher speed, and you can also use the cruise control to keep the speed constant.
Can a low tire pressure light be a false signal?
However, the system may fail and send wrong signals to you. Typically, a Tire Pressure Monitoring System (TPMS) will illuminate. It happens should the tire pressure drop. It will precisely light up if the pressure drops 25% below the required value. In our case, the TPMS may be issuing false signals. What can you do?
Disturbed or Tripped Sensor. If you’ve recently had your vehicle serviced and the tire warning light activated immediately or shortly after, it’s likely that something tripped one or more of the tire pressure sensors. Some models require the TPMS to be reset after adding pressure.
