How to reset your tire pressure gauge?
Your tire pressure light is an important reminder to restore your vehicle’s tire pressure when it is low. Do not attempt to reset the light until you have first checked the tire pressure in each tire.
When your tires are properly inflated, the light may turn off by itself. If the light does not go out immediately, driving at 50 mph for about 10 minutes will reset the tire pressure sensor.
If the tire pressure indicator is still on, you can try a few more tricks:
Turn the car key to “On”, but do not start the vehicle. Press and then hold the TPMS reset button until the tire pressure light flashes three(03) times. Release the button and start the car. The light must be extinguished within 20 minutes.
Disconnect the positive battery cable with the vehicle turned off. Turn on the car and press the horn for three seconds to discharge the remaining energy. When you reconnect to the battery, the tire pressure light will be off.
Inflate all tires (including the spare tire) to 3 PSI and then completely deflate. Inflate the tires again to restore the light.

Is TPMS the same as a tire pressure gauge?
Image via Unsplash by introspectivedsgn. TPMS stands for Tire Pressure Monitoring System. The tire pressure light is part of this electronic system and provides a visual warning when your tire pressure is too low. TPMS monitors tire pressure indirectly or directly.
An indirect TPMS measures the speed of each wheel. If a wheel spins faster than expected, the system signals your vehicle’s computer that something is wrong with the tire’s rotation and the tire pressure indicator lights up. So, You must manually reset the monitor in an indirect TPMS system.
A direct TPMS uses pressure sensors in each tire to accurately monitor tire pressure. This is a more accurate alternative to an indirect TPMS system. The batteries in these sensors last about to 10 years.
Direct TPMS system resets automatically after the tires are inflated or rotated. When you get new tires, you need to have these sensors re-synchronized, which requires a special tool.
Can cold weather or winter cause the tire pressure light to come on?
Yes, cold weather affects the air pressure in your tires. Your tires will lose one to two pounds per square inch (PSI) when the temperature drops 10 degrees. Cold air condenses while warm air expands. Therefore, the cooler air in your tires takes up less space at lower temperatures.
You may notice that your TPMS light only comes on briefly in the morning on particularly cold days. After about 20 minutes of driving, the air often warms up and expands, restoring the proper pressure in your tires.
If the light remains on after 20 minutes on the road, inflate your tires as needed to restore proper pressure. Regardless of the cause, low tire pressure is dangerous for your vehicle. How to Reset Your Tire Pressure Light?
Why is my tire pressure indicator light on even though my tires are good?
When the tire pressure light comes on, the first thing you should do is check the pressure in each of your tires, including the spare tire. Check the manufacturer’s recommendations to determine the correct pressure for each tire.
This is usually between 30 and 35 PSI but can vary. You should measure the tire pressure when the tires are cold, i.e. has not been used in the last three hours.
To check the pressure, simply loosen the valve cover and insert a tire pressure gauge into the valve stem. The meter gives a clear measurement. Put the valve cover back on when you’re done.
If all tires have the correct pressure, there is a fault in your TPMS. Take your vehicle to an authorized dealer to diagnose and repair the problem. How to Reset Your Tire Pressure Light?
Can I continue drive with the tire pressure warning light on?
If the tire pressure light is on, you should check your tire pressure as soon as possible. Low tire pressure is a serious hazard on the road According to the National Highway Traffic Safety Administration, 738 people died in tire crashes in 2017.
When tire pressure is being low, the tire has more contact with the road. This can cause the tire to overheat, which can lead to tread separation, excessive tire wear or blowout. How to Reset Your Tire Pressure Light?
Low tire pressure also negatively affects your fuel efficiency. You can save up to 11 cents per gallon by simply maintaining proper tire pressure. You also save money when you change tires with sufficient pressure.
Maintaining proper tire pressure can extend the average tire life by 4,700 miles.The tire pressure indicator gives you valuable information and should not be ignored. How to Reset Your Tire Pressure Light?
Do I need to replace my TPMS when I get the new tires?
You don’t necessarily need to replace your TPMS sensors with new tires, but now is a good time to check them and make sure they are still in good condition. How to Reset Your Tire Pressure Light?
If you have an indirect TPMS system, your technician must manually reset the sensors after your tires are rotated. If you have a direct TPMS system, then no additional maintenance is required to reset the system.
A new TPMS system will typically last about 10 years before the batteries die. If you have an older vehicle, then you may need new sensors every five or six years. Your mechanic can advise you on the best time to replace the TPMS sensors on your vehicle.
When new sensors are installed, the system must learn about the position of each tire, which requires a detailed series of technical procedures. You should leave this task to a professional.
